Unfortunately, I was bitterly disappointed at receiving the goods. The manufacturer / distributor does not hold, or only partially what it promises. Firstly, the color change function only with a matching (not supplied) AC adapter and is then permanently switched on and secondly, I have not figured out how it would work with the light make night. The guidance does the rest by being very, very, very short and not even it refers as the LED color changing function can be switched on. This is what I found out only in the English section of the manual. The description and the operating instructions should be added to above mentioned points.
