The band itself is fine. The Brightness Control is good, allerdigns the two bands have slightly different colors. The tape is easy to install and the adhesive force justifiable. The power supply is, however, plenty hot and the biggest problem: The Remote Control! Responds only if you get up and approaching 2m to the recipient and then only at the third attempt (and yes, the battery I have changed). The service of the dealer is abysmal or non-existent. Written three times, three times only an automatic, written in bad German answer with vertröstendem text and then nothing more. Will probably have to put up with me, dismantle again is not feasible. Even with the price Leistugnsverhältniss: Once and again nei.
