Actually a nice device, the fan is a little loud, but I wanted the unit in the trunk operate thus would not really bother me. The problem is a completely different, it should be somewhere in the car have a power amp or powered speakers, I suggest that anyone from buying. It causes it on the radio a loud noise so that you no longer hear the music. Even when I tried the device to the cigarette lighter in the front of the car to operate around 3 meters from my power amplifier in the trunk were clearly heard the noise.
I then tried in another car with powered speakers to operate it, as well as just unbearable noise. Away even with direct connection to the battery, or about 4-5 feet from the amplifier in the trunk, the noise is unbearable. Because the thing ansich makes his service there are 3 stars. Thus, but unfortunately not for me.
