Service on top, quality product

I purchased this receiver and handsfree my car.
Aesthetically, the product is well finished and is qualité.Un magnetic base allows to fix it on the dashboard. The center button is lit in blue or red according to different states of the product. This does not always see in daylight but once the pairing was done we do not need to know the status of the receiver. At this point, the edge of the button lights up blue and flashing.
The center button is used to start pairing, answer / end calls and play / stop the song.
It has 2 buttons Other buttons that increase / decrease the volume (short presses) and go to the previous / next track (supports long).
An on / off switch is located on the east side allows to turn off the receiver without necessarily disconnect the USB plug. My transmitter is powered by a USB socket of my car stereo (extension in my glove box). This saves me from having a cable running through my console to the cigarette lighter, which is next to the gear lever. So I did not use the cigarette lighter supplied with the receiver.
The version I have a small problem with the buttons to select the previous or next song. The shares are reversed. After contacting with the service, a new version that fixes this problem will be out soon and will be available on Amazon. Before buying ask the seller if it is a corrected version that you will send or not. The service is responsive and that's what earned them the last star;)
