No connection problems and quite satisfactory sound. 5-6 hours of continuous music comfortably. One star - because it has a micro USB cable and not type C.

It worked for about 5 months. Good sound etc., but the person I was talking to couldn't hear me + just before it went to the trash it wouldn't charge because it didn't make good contact with the cable. For its price though, it's fine, no complaints. However, there are better options for this money if you want something affordable

Guys, very good! Crystal clear sound, very decent battery life, and you have the option to use either an adapter or a 3.5mm jack cable, which for the way I use it, was very convenient for me.
P.S. For those who want to use it for calls, the microphone does not pick up sound from a distance. You need to keep it relatively close to your mouth to be heard.

Very good for music but not suitable for phone calls due to the microphone. Very good battery, connects very quickly but you need to turn it off before you leave the car.
The sound quality drops as the volume increases and it distorts when it gets close to max. At medium volume, it is not noticeable.
It is an extremely economical solution for someone who does not have a BT connection with their audio system, whether it is a car or an amplifier, as long as there is an AUX port.

I've had it for a very long time, it's perfect. The only small problem is that it is glossy all around and over time in my car it has become dull and has gotten scratches and marks. But that depends on how each person uses it

Excellent gadget. It does exactly what it promises. Connects quickly, has crystal clear sound, the microphone works great for calls in the car, and you can also change tracks from the buttons.

Very good, as soon as you turn the ignition it connects. The only negative is that before you get out of the car you have to turn it off because even if you turn off the car it remains active and your phone stays connected to it all the time

The microphone does not sound good and when it is connected, the use of the radio stops, which is inconvenient

Good battery, immediate connection, but the microphone is not good enough for conversations through it in the car

Very good, connects immediately. Minimal reduction in the radio's sound volume. Excellent for its price.

It has saved me. It connects easily with iPhone. No problem in the car. Its battery lasts for a three-hour trip.

It does what it says. I didn't have any particular issue with the connection and I have it permanently on charge so I don't have an opinion about the battery life.

It is the most economical solution to have bluetooth in an old car. I had also tried a radio transmitter that was constantly buzzing until I threw it away. This one here has crystal clear sound! Many users say they can't change tracks, but I can change them normally. Long press on + takes me to the next, long press on - takes me to the previous.
Excellent product, value for money!

Very good sound quality, it turns off by itself if you forget it. The battery lasts about a week with regular daily use.

It connects easily, you hear well, they hear you well. You listen to music via aux, you do all the functions from the phone.

It does its job very well and has very good call quality when I speak, even though I don't have it in such a good position, but it definitely worth the purchase for something affordable!

Very good, it converts aux to Bluetooth without any problems connecting to various mobile phones. One downside is that the volume drops a bit, but for the money you spend and the job it does, it's a negligible issue

Very good for use in an old car. The bluetooth doesn't have any interruptions at all. It also lasts a very long time. I can't say for sure, but on a trip from Athens to Sparta and back to Athens, it didn't need charging. The battery might have reached halfway, maybe a little below that.

It worked perfectly in the car, I had it permanently connected to the USB of the source and it was always fully charged.

It looks good, connects quickly, has audio messages for connection, activation, etc., unfortunately the buttons only change volume and not song. It disconnects during video recordings.

Very useful gadget, I use it in the AUX port of a Peugeot 107 and connect it with an iPhone. It activates by pressing the button for 5'' and connects directly to the phone. Music plays just fine, directions from Google Maps, I can be heard without any issues during calls. The button is also used for play/pause and for answering calls. The only thing I would like is the option to change songs, but it's okay, it can be done from the phone as well.

For music, it's great; in calls, it has an issue with Android phones as it doesn't connect directly for talking, but it worked better with iPhone. The battery is okay, not something amazing in terms of autonomy, it lasts about 4-6 hours

Very good choice if you have an AUX port but not BT on some sound system. Very good battery life and good sound. The only negative I noticed is that when the volume goes up, it produces a slight buzzing, which I wouldn't say is a problem.

It connects instantly by pressing the only button it has for a few seconds. Searching for new devices on the phone will find it and connect without any problem. I have permanently placed it in the car connected with USB to the lighter. I haven't needed to reconnect it; every time I approach the car, it connects automatically. The only downside is that the volume of the music has decreased a bit. Otherwise, it's an excellent gadget.

The low sound level is the only problem. That's why 4 stars. Battery life and sound quality are the positives!

It works well. Easy pairing. Unfortunately, it doesn't have a button to skip songs. Instead, it has one for the volume, but I think a button for skipping songs would be more useful, since we can control the volume from the car itself... but since it works well, it's a minor issue.

Very good and useful.
Relatively easy connection with Bluetooth and the battery with normal use can last several days (about 10-14).
Of course, it is not good at answering calls at all, because no one ever hears anything. If you want it exclusively for music, it is wonderful.

Very bad product. It connects and disconnects constantly, and after 6 months of use, it stopped charging

Good sound overall. Fast connection.
At first, the battery lasted longer, I can't say it had a long duration! Until suddenly it doesn't charge... I connect it normally to the charger and nothing... Until it ran out of battery!

Works great, nice deep sound, and everything is good on calls. Only a small issue with battery life
