The delivery was fast and well packaged, the product itself is really great. The colors are very good, so far (10 days) and no losses, the installation was easy. The color changing speed can be adjusted the way. I had previously read that the color changes were much too hectic, but it turned out that in the Switching Modes a long press on the remote control Dimmtasten regulates the speed of the color change. From strobe effect to a snail's pace, anything goes. Only the white is very cold and the color temperature is not even regulated, super for Deco effects, but as room lighting unfortunately unsuitable. Better Electronics were here class, for the price you can not expect that but.
Conclusion: thumbs up and I buy probably soon have one or two more sets.
