All was well when after a month of use it started to get stuck on one frequency, helplessly else. Yet it was used in the rules: connected to the cigarette lighter socket only when the engine was started ... Too bad! In addition the "rod" which connects the socket to the transmitter itself is too long and very little malleable. The screen is small, it is impossible to read anything at all while driving. Otherwise the sound was pretty good and strong enough, without crackling (jhabite campaign). I still recommend provided they do not fall on a model that bug!
