I, too, was only slightly sekptisch whether a device that is so hot, longer lasting. I have it now for almost a year, and it still works !! Finally hath everlasting CD burn an end. Load the USB stick after momentary mood in the transmitter in order, and off you go (actually best with the "Miracle frequency" 87.5MHz). A star deduction there because of some missing features: If the car only briefly, the current song is played from the front (I have a novice driver in the family ...) and even the unit will not switch to the next folder. But the key 100+ to get further a folder. Newer remote controls but is also a Folder + u. Folder- button. Amsonsten: sound good, price great, full purchase recommendation! PS: After the 3rd device same manufacturer I am trying it with the slightly higher priced Tranmitters from Mumbi. .... It was always so stupid little things, where it failed: even broke the USB port on the enclosure and vanished into the device, once broke one of the two plastic barbs which provide a firm grip in the cigarette lighter, off and a working the same for non-receipt. If the sound and the price would not be as good, less star came out here much. But Amazon refunded so very reliable!
