The connections for micro / speakers are glued wrong with 3 of 5 devices. The Micro can be infected yet, but it looks terrible. For 1 device, the antenna lies screw only with a little persuasion, was caused by a ridge on the thread.
Also was 1 of 5 chargers defective and I can now for days with around discussing "The Good" if I get it replaced. However, this flows only in my Shop Rating, not to the product!
One drawback is that although car adapter are included, however, for loading in the car and the charging unit must be used. Direct plug in to the radio is not possible. Furthermore, one should read the order carefully, there are a set of 5 with programming cable and a set of 5 with microphone without programming cable.
With a little reading in the (German) manual also works programming but no!
