Processing (plastic) can look very sophisticated, which I expect at the price. Unfortunately, the lamp is still missing dimming function, since the LEDs are highly luminous ... Although is super to a large room (bedroom / living room) illuminate, but sometimes I love it comfortably, so there is only 4 instead of 5 stars. Also, I would like to say that the touch panel is not always 100% accurate responding, but I think you can still tap twice on the right color. :)
