USB rechargeable LED Chameleon 2.0 set for both sides, micro USB Type-B, to be attached to a diabolo for juggling. This is a set of two (for one diabolo). I haven't used it much, but the white light on one side is not working. The others are fine. The battery life is almost the same as when I bought it, and there is no degradation. Except for one white light not working, there are no problems with the operation. Only the two unit parts shown in the photos will be shipped. I am careful with the packaging. Please consider.
