That in this small design a 16-stage dimmer is accommodate with additional effects, if I had not thought of. So far I have only testweise operated him a 120cm LED strip. I hope he comes as well with larger benefits. Radio interference in radio or TV I did not notice. In addition to 16 levels, there are also various flash modes, which of course is mostly superfluous in the living room. The wireless remote control is working fine. I'm going as a precaution still another dimmer (seller NEON-Mart, Merchandise was the next day there) pick, so I have the same replacement in case of defect. A return is worth at the low price hardly.
