This is the second transmitter that I buy and I'm really happy.
It is handy while traveling, with FM transmission quality and ability to change easily the frequency in case of conflict with local FM stations. I got used to the easy use while driving, the goal is reached.
I use it mainly with SD, the sound volume is less good with my USB key.
Browsing the mp3 support can be by folder or song. If many directories / songs, keep nearby a small note with the main entry points (our floor), one can thus easily change, driving the playlist to listen to.
Remote controls are working properly. Personally, I use the remote control volan least, it must be aligned with the front of the transmitter for IR transmission with the device.
I had trouble with the grip, then 10-15 minutes I had to go to browse the small guide sold with the apparatus cleared up the terms of use.
Bluetooth transmission with the mobile (Samsung Galaxy) is done correctly, however you have to "reconnect" the phone to each restart. (Bp is the mobile phone side, there may be an option for automatic reconnection).
Only real inconvenience: the unit does not remembers the precise position of the last reading when stopped. Upon restart, it starts playing the song from the beginning. It's a bit frustrating when you listen long enough music tracks.
Also, but this is natural in such a large system, the information on the screen of the device, very complete, are difficult to read, I have to put the glasses and so I must be off.
Anyway I can only congratulate the designers and marketers for what they put into it, for the price, very competitive (eg simply a brand transmitter without reading function and power transmission significantly FM lower is sold in the same price range).
