Terrible. It worked for a little while, but people couldn't always hear me well. The battery lasts very little. After a lot of heat during the summer, half of it melted. Because of all these issues, I rendered it useless.

Average build quality, poor (in terms of quality and volume) sound.
Its low price, therefore, has its justification!

Very good for its cost, the support base is very sensitive, but it can be supported with Velcro. It works very well.

The charger has a problem and does not make good contact when you connect it to the car. On the USB side, it is so loose that it came off the circuit board during the second charge. Ten euros wasted for nothing...

Good for the money it costs.
The only "issue" it presents is that its microphone is not that powerful, resulting in the person you are talking to not hearing you well.
However, it has a pretty good speaker and you can hear the conversation clearly

I received the car Bluetooth today, I tried it and I was honestly amazed. Although I still don't know how to operate it very well, the sound I heard is more than fantastic. I believe it's worth it
