UPDATE 16/09/2024:
The watch stopped working for no apparent reason. I put it to charge for a day, and since I took it out, it has never turned on again. When it is connected to the charger, it works perfectly, but as soon as you take it off, it’s dead. I assume the battery completely failed without showing any signs. I’ve had it for a few months; its battery lasts me 6-7 days.
During workouts, it often completely loses the heart rate function and then shows random numbers for a few minutes, like 50 beats after 20 minutes of running on the treadmill (I personally don’t have 50 beats even when I’m sleeping, let alone after intense exercise).
I can’t explain why, but while I’m running, it seems to work perfectly, at least compared to the readings from the treadmills or the bike; the heart rates have no deviation between them, nothing, zero. The problem always appears when I stop recording that particular exercise, like when I finish running and go to the next recording, like strength training. That’s when it freezes and shows random numbers.
Other than that, it’s an okay watch, beautiful with a wonderful bright screen; app notifications, etc., always work and work correctly. Aside from the problem I outlined above, I have no other issues.

At the price it has today, I think the watch is very fair, if not a bargain, around 80 euros. I've had it for 3-4 days... The watch works perfectly with calls; you can answer calls, but not make them. It's like having hands-free with speakerphone, which is very convenient for me. It's not suitable for all situations, like if you're around people, because you'll be talking in an open conversation, but now at home or if I'm out on my scooter, I can stop and answer all calls from the watch! The battery lasts a week considering its capabilities, which I find satisfactory. You can read entire notifications in Greek. You can set up apps like Messenger, Viber, WhatsApp. I've only set up the essentials to avoid being bombarded with notifications and to prevent unnecessary battery drain from pointless alerts that would wake the watch. The screen is nice, and the menu is fast. In conclusion, I would say the price is good now... it's not worth it to go for more. Watches will only get better every year, just like phones... only watches are still in their early stages. If you’re not interested in answering calls, you can get a smartband for half the price. For example, I previously had a Huawei smartband. I don't comment much on health features because, in my opinion, they all have more or less the same capabilities, and I don't have crazy demands in this area... I prefer to see steps and sleep tracking, which a simple smart band does just fine. The GPS it has is unnecessary for me, unless you're someone who competes in decathlons and needs precision :P It's a bit annoying that it has Amazon Alexa for voice commands but needs a workaround to work in Greece since Amazon hasn't come to Greece yet. You probably need to declare a foreign country on your account, and you might have to create a new account... It could simply have an option to change the country to unlock it... It could have a slightly more quality strap... it's not ugly, but you wouldn't call it premium... The shape of the watch with the strap has a slightly awkward fit on the wrist, causing the watch to rotate a bit if you don't have it snug on your wrist.

Beautiful, sits on the wrist effortlessly and without feeling it since the dimensions, thickness, and weight are quite limited and ideal even for a slim wrist. It features an excellent display, with automatic brightness adjustment, and is clear even under strong sunlight. Countless watch faces are available through the official app but mainly from a third-party app available on the Playstore. It does (not always) recognize calls from contacts, and you can answer with very clear sound from the watch, but you cannot make calls as it is not a smartwatch but a Vfm budget fitness watch. However, you can read notifications and messages from apps that you specify.

Its heart rate monitor is quite reliable as is the oxygen measurement. There are small deviations in fitness and GPS measurements. It has more than enough fitness programs and various other "goodies" like alarms, weather, sleep tracking, stress monitoring, phone finding, automatic exercise recognition, etc. With automatic brightness adjustment, and the heart rate monitor, sleep tracking, breathing, and stress monitoring always on, the battery lasts 5 days. If you activate the always-on display feature, the duration drops to 2 days. Perhaps the delay when opening the screen with a wrist turn annoys me a bit and could be slightly shorter without ultimately being a concern.

In case it disconnects from the phone, you will need to turn on the phone's GPS to locate it again within 10-20 seconds.

Having owned it for 10 months, purchased for €96 (Skroutz offer), I believe it does its job more than fairly for the price it asks. It is not a smartwatch and it is not a pure fitness watch. However, it gives you the ability to monitor basic health and exercise functions and makes your daily life easier with its features in a very beautiful package.

After 2 weeks of use, I have the following to say:

1. For its price, it is the best available with the biggest advantage being the battery life, which with all functions on lasts around 5 days without difficulty.
2. Notifications, clarity, battery, and autonomy are at very good levels.
3. Regarding the measurements, there are losses and inaccurate readings which occur from short walking distances (from the kitchen to the living room it may not even start measuring), resulting in losing quite a few steps throughout the day compared to what the phone records, which has very accurate measurements.
4. The speaker and microphone during calls work flawlessly, especially the microphone is very loud and you can easily hear your conversation partner even in an outdoor setting.
5. Fully waterproof, I have swum twice and used the "open water swimming" mode. The screen locks automatically to avoid being affected by drops, and once you finish swimming, it provides an accurate route covered based on GPS, time, type of swimming you did, as well as heart rate and number of strokes.
6. Running only on a treadmill also had losses regarding the steps it measured.
7. A very positive and convenient feature is that the app keeps a complete history of all activities. However, it could have more options for watch faces in each category.
8. It is very stylish on the wrist, very lightweight, and can easily be worn even with more formal attire.

If no serious issues arise in the future, regarding some comments I have seen from other users, then I consider it one of the best value for money purchases I have made, and overall it is one of the strongest options currently available in this price category.

I have the SPORT edition.

I bought it about a month ago and I am very satisfied...

Suddenly, everything I wrote in my initial review three days ago has completely changed:
"Only the battery life concerned me a little because it doesn't last more than 4 days until it completely drains, but I have quite a few 'Health Monitoring' features activated out of curiosity. I also have (for my activity hours), the screen on 'Always On Display' which also consumes the battery quite a bit."

For the past 26 hours since the last charge on a USB computer, with the exact same settings, it is consuming extremely little battery. The battery probably settled from the fast charging I did during the first charges or the battery found its overall duration (this happens with lithium batteries, they find their total capacity after a few charges).
So, after 26 hours it has only lost 15%, which leads us to conclude that it will drain in 175 hours (hypothetically of course)!!! That is about 7 days, significantly more time than I recorded after the first charges...!!! I won't keep it uncharged until the battery drains, I don't recommend that for lithium batteries, but I will charge it when it's around 25% and I will calculate how long it has lasted by then.

It is beautiful, lightweight, you get used to it very easily in your hand, it looks quite durable, especially the Gorilla Glass on its face. Although the silicone strap is comfortable, it seems a bit vulnerable. There are thousands of faces available to put from the Amazfaces app. It needs a little trick of toggling the Bluetooth switch for the app to see it when the handshaking between the phone and the watch starts, but that's okay.

Also, when the sound stopped working at some point, I simply rebooted it and it came back immediately!!!

For a first Smartwatch, I find it excellent, due to its impressive screen, very beautiful design, ease of the menu, and clearly its low price.

I haven't explored in depth its capability to become a tool for someone who is professionally involved in sports, but I think it is more aimed at amateurs. Anyway, as a watch, it is extremely convenient and user-friendly!!!

Importantly, I receive all my notifications, SMS, emails, Viber, WhatsApp, Messenger, app notifications, etc., as well as calls to my mobile, even waiting calls that I can answer and talk on the watch if I am within the Bluetooth range of my phone.

The vibration for all notifications is excellent and fully customizable!!!!
You can create your own vibration pattern for each type of notification. It also has notification sounds, but I have disabled them because the vibration is always extremely noticeable, so you don't even need to have the sound on your phone active... You will feel the vibration, you will see on the watch who is calling you or what the notification is, and thus you will decide whether to pick up your phone, always having the option to decline the call from the watch... The fact that you don't need to have your phone exactly next to you (also for radiation reasons) and at the same time you don't lose touch with whatever comes as a notification is extremely useful!!!

In general, it has a lot of settings for all tastes!!!

It DOESN'T have a keyboard of course and you can't reply to messages naturally.

A small bug that I hope will be fixed with some update... When you receive a call from someone (missed) and someone else calls you, the recognition repeats the name of the missed call and you think the other person, the "missed" is calling you, and so you don't know who is actually calling you at that moment. I don't know exactly when and why this happens, but twice the recognition showed me the name of the previous missed call while someone else was calling me...!! It might be that one has to press the "X" of the missed call on the mobile screen to erase the missed call from memory... I will check this thoroughly and get back to you...

The app it uses is Zepp and on my mobile (which is Apple), it works excellently. I only needed a little time to connect it properly and have full recognition of my calls, but in the end, everything works perfectly.

I recommend charging it via USB from a computer so you don't damage the battery or with a charger not larger than 0.5A...

It takes about a minute for every 1.2% of battery. In 5 minutes it charges 6%.

I have swum with this in the sea, everything is fine, I followed the instructions for rinsing with fresh water immediately after swimming in saltwater. It recorded my "performance" in swimming, but I don't know how accurately since I didn't pay much attention. The "Open Water Swimming" app locks the screen automatically so it doesn't "go crazy" from the water droplets that randomly activate various commands otherwise.

There is also a good Greek menu, but I prefer the English one out of habit.

I recommend it as a first smartwatch. I will get back to you when I put on a new strap, I'm waiting for it to be delivered...

In the last image, you will see how it looks after setting the screen to "always on display" which shows only indicators or generally something quite less than what the active screen shows (depending on the face option) for battery saving reasons. In this case, the last two images are the active screen (I have set it to last for 10 seconds) and the corresponding "always on display" screen (all of these are adjustable with a plethora of options).

A small update regarding the battery:
Since I got it, I had set the "always on" which gave me 5 - 6 days of battery, having almost all the "Health Monitoring" features turned on (except for All Day Stress). Turning off the "always on" for the continuous display of the time brought the battery duration to 8-9 days. Extremely convenient.
I imagine that if some or all of the "Health Monitoring" features are turned off, the charging duration could increase significantly.

As a smartwatch, it is quite good and has a nice appearance on the wrist. Easy synchronization with the mobile phone. Good speaker and microphone for talking on calls. Very nice screen with clarity. As a sportwatch, however, it falls a bit short. It has many activities to choose from and provides quite a bit of data such as elevation, incline, speed, etc. for walking/running, but it doesn't have a way to keep sets or laps to maintain control. For example, I look at how long I've stopped and measure my breaks accordingly, which bothers me during interval training. The battery lasts quite a long time, I think, since I use it every day as I work out 6 out of 7 days. It charges quite quickly. The measurements are close to the actual ones, mainly in kilometers (based on the mobile phone, but it has happened to have a deviation of 600 meters), as long as you wear it tightly. Lastly, while it has GPS, it doesn't provide GPX files on the watch to view routes. What it does is keep the route, and you can see it from the app on your phone along with the complete details of your workout. I made an attempt to transfer GPX files from the computer, but I couldn't figure it out and gave up. That's it. Overall, I recommend it for the price. You can wear it outside, and since it is "glamorous."

Purchased a week ago. Here is a brief description, but below I also have a link for anyone interested in seeing a detailed review of the watch.

Positives
1. Good measurement accuracy
2. Very good display
3. Quality construction, lightweight and comfortable on the wrist
4. 3Gb space for music (slow transfer from the phone though)
5. Ability to connect Bluetooth headphones (very good volume and quality levels).
6. Satisfactory battery (about 5 to 6 days, with GPS during workouts, music with headphones, notifications, and sleep assistant)
7. Call acceptance with good speaker and microphone quality
8. Some extra features in the software

Negatives
1. With the Mi True Wireless Earbuds Basic S, I had to wear the watch on my right wrist to avoid connection issues while listening to music (many issues on the left, none on the right wrist)
2. The GPS may take a little while to lock initially and has slight inaccuracies here and there (it could also be the area, as there are no inaccuracies in more open areas)
3. Average UI performance (possibly for energy saving)

-Personal detailed Review-
https://youtu.be/e5TXkbzFEbI

The smartwatch was purchased about a week ago and I think it approaches perfection for the given price. (Sport Edition)

Starting with the positives, the first thing you notice is its very beautiful display, amoled with very good clarity and resolution. The response is incredibly fast and its speed is ideal without any lag. The functions you will notice later are many and very useful, such as the setting for which side you want the two buttons to be on and the function of the second button (to be used to open workouts or anything else). Even something as simple as that makes the user enjoy it to the fullest.

As for the sensors, the heart rate sensor is very good and accurate, the steps are counted correctly, either a few less and not more, unlike other smartwatches of a similar budget. I haven't tried the oxygen meter, however, they say it has a small (albeit acceptable) deviation since it doesn't guarantee medical accuracy.

Its battery during heavy use due to the first days, with the new updates, exercising 2-3 times a week, custom-made watch face, and all functions active, lasts from 4 to 6 days. With a sacrifice of a few functions, I believe you can reach 8-9 days.

Now regarding the GPS, the truth has been stated below. Significant losses with stress control activated and Bluetooth on. If you turn them off, its accuracy is very good, so with a good update in the future, this issue may be corrected since the sensor seems to work well as a sensor. If necessary, a restart or a factory reset might somewhat fix the problem (which I haven't tried yet). As for the delay it takes to find a signal, it is very small (around 15 seconds).

A few more details: The microphone works very well, as do the voice commands. The speaker is excessively good to the point that I didn't expect it. It's a positive fact that it has storage space, but also very convenient. Easy menu and a huge number of functions that will really be useful to you.

I particularly liked the initiative to enter Do Not Disturb (DND) mode at night after you fall asleep, so the sound doesn't disturb you at night.

I had a little issue with the weather synchronization, it might be the phone's fault, and as soon as I turned off the automatic location detection and set it manually, it was perfect.

For anyone who doesn't know, it recognizes Greek perfectly while you have the option to have the menu in Greek.

As software, it is one of the most beautiful, with very vibrant and beautiful colors. Many workout modes and lots of information about them, while you can return to the home screen while exercising.

Finally, regarding calls, you cannot make calls, it doesn't have contacts, but you can only answer calls. The call quality is very good.

For the given price, I think it deserves at least 4-5 stars because for that money it is top-notch! The only thing it needs is a good firmware update to fix bugs that were created due to software and not hardware. At €130, you won't find anything better in my opinion. In appearance, it is undeniably a very beautiful watch, and with a better strap, it looks more expensive. Very convenient and lightweight on the wrist, while the buttons are positioned in such a way that they do not bother the hand in any way, not even when bending the wrist.

After a week of use, I have to say the following... compared to the GT2, which is its main competitor... it is much better in many ways... it has auto pause on any device, whereas the GT2 requires a Huawei device... it syncs with Strava, which is very important for a sports watch... but the most important thing is that when you start a workout, you can navigate to other functions of the watch without leaving the workout screen... this way you can check messages, see the weather, etc., something the GT2 cannot do... as for the battery, it's exactly the same... sleep tracking is much better and it doesn't stop recording if it loses the heart rate... the screen is the same... the heart rate has a little issue with sweat, something that didn't exist with the GT2, and it also fluctuates a bit before stabilizing... I believe this will be fixed with an update because the GT2 wasn't the best at first either... you can't make calls from the phone, only answer them... the microphone is quite good... as is the speaker... regarding the altimeter, the positive aspect is that besides the sensor, the GPS also works for better results... it charges in about an hour and lasts about 4-5 days with 3-4 hours of exercise a day and only the screen off... I believe for its price, it is the best now since its competitor has some significant shortcomings...

Owner for a month and something now I have to evaluate as follows:
- Battery!!! It fully covers me. It lasted 1 week from the moment I got it with continuous use to familiarize myself and 4 workouts of 45 minutes (outdoor running and cycling). With the second charge, 12 days, and now I am already at 8 days with 3 workouts. Open Bluetooth from 7 in the morning until 11 at night with push notifications and calls from the watch. SO: it’s perfectly fine, it covers me, it's worth the money for its battery.
- Screen!!! The best I have ever held in my hands among garmin 5x, vivoactive, and huawei gt. Generally, an amazing screen and very clear. The touch is exactly as it should be, and I have also placed a zag protective film to be sure. It hasn’t lagged at all so far and responds perfectly. SO: among the things the watch promises, it’s worth its price.
- GPS!!! Reading I know there has been a lot of fuss. Initially, let me say that I bought it for 169 (I wanted a 2-year warranty and immediate delivery) so I didn’t GET a Garmin. So I didn’t expect Garmin accuracy. In terms of the race, however, very bad for nothing. On a measured route of 4 kilometers, it measured correctly to the centimeter. Of course, after the zepp, I saw that I was a bit (and I mean it) like Casper the friendly ghost, but, guys, it measured correctly. That’s what matters to me. It never dropped or lost signal. I haven’t tried it in the mountains, and if I go, I will return. SO: again, it falls within the range for an amateur athlete of short and medium distances.

In general, don’t expect a watch that costs around 150 euros to do what a 500 euro one does. Don’t exaggerate and be aware of what you are getting. It was purchased to measure steps, heart rate, and 3 workouts a week. It does what I want, and I am satisfied. If you are a professional athlete and want something more, don’t be stingy. Enough with the reviews where you compare everything to the top product that is 2 to 3 times higher in price and everything seems terrible to you.

For anything else, I will return...

UPDATE 23.5.2021: I found one negative for me. It doesn’t record my afternoon nap, although I would really like it to. I also tried swimming in open water, and it showed that it was losing GPS.
