The order was delivered on time. Everything was as described in the store. It works perfectly with the Garmin FX 6Pro that I have.

Good belt, good measurements. However, with daily use, the buttons that the sensor attaches to the belt rust, and then it needs to be replaced.... After 2 Garmins, I switched to another brand.

From experience with already 3 sensors purchased, they work ok until the battery replacement. After that they give crazy values

Guys, about ten years ago this belt was amazing, I had it for so many years and just changed the batteries and it worked like new. Now this "new" version is indeed problematic, I have bought 2 and at first the first one didn't work at all, meaning it didn't connect to the watch, I changed the battery and it still didn't connect and was sent back as defective. The second one shows unreliable readings constantly, one moment 180 beats while I’m running and suddenly 80 beats... don't buy it, others say the same

Stay away from this belt. I got it with a gift voucher and it doesn't connect with any app, not even with the Garmin app. I mean, it's tragic! On top of my bad luck, I happened to have the Garmin Instinct, which might be the only one that connects, but the problem is that the Instinct also has its own sensor and shows heart rates, so I don't know which is which. It didn't even come with user instructions. 2-3 days of searching on the internet easily...

Generally very quick readings and convenient, after a few months of use it started giving random readings in the middle of the program like 175 beats at random moments downhill (I measure both by hand and with a pulse oximeter) resulting in my mind drifting from how I run to thinking that I'm doing the program wrong, conclusion is that the electronics simply break down very quickly, it's a shame because it's a good product overall

Stay away. It easily absorbs moisture and looks all messed up. With a new battery carefully installed and the seal properly placed, no results. Polar and again Polar!

The first belt lasted almost two years. Today I bought the second one. Surprisingly, the black clasp of the first one had broken, not the belt as usual from what I see on the internet from others (it wasn't the battery, I have changed many). So I will use the new clasp with the old belt and keep the new fabric belt as a reserve. If it lasts another two years, I will be satisfied because from what I understand, these devices break and I don't want to buy something even more expensive.

One of the worst belts, I don't know why they have come out faulty, every belt I got had the same issue. I have changed the belt 4 times and still the same. It works perfectly for the first month and suddenly at some point it stops counting steps and heartbeats, nothing works. And if it does work, it shows that I have 70-80 heartbeats while I am working out at least at 160+. I have changed the batteries and washed it properly, but still nothing. Maybe it's also my Garmin's fault, which I don't think so, but still, every time I got it, it turned out to be faulty

The worst thing there is. I have changed 4 zones. If you use it regularly, it has a lifespan of at most 10 to 14 months. It constantly loses connectivity and shows random pulses. They replace it with your warranty after 20-40 days. But you are left without a zone during those days. It is better to choose a zone from another company.

As long as it worked, it was OK. After 6 months, it broke. It started eating up the battery and in the end, it completely lost connectivity, even with new batteries. Disappointing.

Instant connection to fenix 7X. Relatively uncomfortable while running compared to other watches as it feels slippery and if I tighten it more, it presses on me. Additionally, after 2-3 months of use, the side straps started leaking

The usage month is working properly. With the HR2VP app for cyclists & Zwifters, you can convert HR -> WATT. Make sure to put enough water on the sensors for accurate pulse recording.

Currently (after 2 months of daily use), it works well and definitely provides much greater accuracy compared to a regular watch. I think if you don't need it for swimming, there's no reason to go for a more expensive model. One positive aspect is that the transmitter can be detached for washing. A tip: wet the sensors and the contact point on your body a little before use to ensure accurate measurements and a stable connection.

Very fast connection and measurement accuracy. I have not encountered any problems related to the band. It is important to wash by hand.

The first six months went well, but then it started to frequently malfunction. I changed the battery, but the problem persisted. Now I will turn to Polar, which I consider to be a one-way street.

If you use a Garmin watch then 4*. For me, it was excellent as long as it worked, but now I have realized that due to the change of Garmin's protocol, I need to have a Garmin watch or activity tracker to upgrade the firmware since upgrading via WiFi is not possible (only via ANT+ from a compatible device with Garmin Connect). The strap wears out due to sweat and unfortunately, it is not sold separately. It is easy to wear, but the initial adjustment to make it comfortable is not easy. I don't know how long the battery lasts (it turns on as soon as it is worn) but I haven't used it for 3 years that it claims to last, but I imagine that with WiFi usage, it will be significantly shorter than ANT+.

His life lasted exactly 6 months, with proper care (cleaning, washing) as instructed. Used on average 6-9 hours per week.
After a few minutes of use, it freezes (the pulses remain steady) and then stops showing pulses.
As a first action, I replaced the battery, but there was no change in its behavior.
I checked it on my phone, laptop, and Garmin Edge 530. The symptoms are exactly the same.
I am returning it to the supplier for inspection and replacement (awaiting).
Update:
To inform you, the problem is clearly located in the belt (sensors) and NOT in the transmitter (which is the black plastic part with the battery).
So if your belt is out of warranty from Garmin, you can purchase any other belt (very economically) that has a distance of 45mm between the two metal slots to attach the transmitter on top.

An essential accessory if you want the highest possible accuracy in measuring heart rate. However, since I have tested it on the same route with the same pace, the watch's measurements (fenix 6 pro) deviate very little from the measurements of the chest strap. I cannot answer for its long-term durability as I have only had it for 1 month!

I have had it for about 2 months, fast connection with fenix 5X accurate in heart rate (compared to the watch that had the sensor on the wrist, about 20+ beats difference). The only disadvantage I see is that the hook they have made does not secure very well, so when you try to fix it during training it may sometimes move or come undone. I would like a better closure system

It doesn't work so well when you're not shaved. Also, after 3 months of use, it has started to overflow. I use it exclusively for cycling and wash it after each use. If I had bought it for 30-35 €, it wouldn't bother me. For 60 €, I expected more.

Only two issues. Firstly, it sometimes takes a few moments to connect and secondly, during the first two months, it caused intense irritation on the skin in the area of the closure.

It was purchased as a supplementary heart rate monitor for my Fenix 3. It appears to accurately measure heart rate. The durability of the strap over time and use remains to be seen.

It connects via Bluetooth but does not show any pulses. It connects via ANT+ and everything works fine. Until an upgrade to Android on Redmi Note 9 S, it can no longer connect via ANT+. Useless

High quality, accurate, durable and easy to connect with the forerunner. It could be a bit more affordable.
Update: After 1 1/2 years, it remains accurate in measurements and has not presented any issues. For those who mention measurement accuracy, the sensors need to be slightly moist. Either wait until you sweat or wet them a little before wearing.

I have completed one month of use, using it for one hour every two days.
It connected very quickly both with the rowing machine (concept2 model D, PM5) and with the Garmin Fēnix 3.
It seems to provide accurate measurements and as a build, it is of good quality.
Just because of the brand name, I hope it lasts over time.
Update after 5 years of almost daily use on the rowing machine and while running. Washing the strap by hand after each workout and hanging it to dry, and it is still like new. I haven't needed to change the batteries. It communicates perfectly with the Fēnix 7 as well.

Good product and accurate in measuring heart rate. The only negative is that with daily use, the belt with electrodes wears out on the rubber. Replacement at some point is inevitable. The cost of which is not insignificant (about 35€).

I am familiar with the product. It is of the same quality as the previous one and has a Bluetooth connection. Expensive, but it's Garmin

Very good product. The belt quality is much better compared to the previous model. Easy removal of the heart rate monitor for belt washing.
