The button got stuck inside and stopped working after 5 days and 5 presses. The only thing that works now is if the power goes out, it turns on.

Very good. It has intensity adjustment and white or yellow light. Its light is not very strong, but it does its job well and is quite safe for babies as it fully attaches to the socket and is difficult for infants to remove. It is also useful as a flashlight.... since it is fully charged every time (as it is constantly plugged in). So when you need it, you simply take it out of the socket and it turns on. You put it back and it turns off. Excellent product, I have already bought 4!!!
