Really nice light. Stepless adjustment of brightness and color temperature. If they would just sell me light it would get 5 stars. But they contained the most incredibly inferior charger I've ever come across. When first connected (mains power) nothing happened. No light, no battery power. Unplug the connector and one of the connector legs will fall off. I could return it but it's either a refund or they send me a replacement with a different crappy charger. As I said the flashlight itself is excellent so I left it and ordered a better quality charger. It ended up costing me a lot more, but now I have a quality tool that I can rely on to work as intended.
