Almost perfect ... 10 5

simple, clever, provide the announced features (auto search, preset tuning, manual tuning, automatic pause) of good quality, much better than what I expected (after purchase and return of a similar apparatus another brand, unusable ... maybe defective, untestable actually).

Only downside - perhaps not related to the device itself, but rather to the car model and / or the audio - I had the chance to try the same FM transmitter before ordering it: Reception was generally excellent and very reliable.
But chance, I had to disassemble the vehicle roof antenna, because next wash.
After winding the antenna, the reception was just catastrophic; under these conditions, the transmitter is unusable.

In the end I kept the FM transmitter, and have re-dismantled the antenna; in town transmit power radios that is sufficient for it to work without (albeit with a lesser quality) but listening to mp3 - who mattered priority - is close to perfection, even in a large Agglomeration (Lyon).

- FM transmitter used with a small SanDisk drive.
