Perfect, not found better

Seeking for years a transmitter that works well I've tried several and worn but this one is perfect; already the sound quality is more than adequate, the bass is there, too acute, Bluetooth works fine, the sound when the phone connection is a plus, the strength of the FM signal is more powerful because for now I never changed frequency and the sound is always clear. The hands-free part is not used very much but I tried it and here the air worked pretty good too.
