I opened the packet to test the first one and it didn't work. Then i noticed the small pull tab at the battery would connect. Bingo everything was then working. I charged them up but they already seemed to be mostly charged. The lights are bright and the switch ready to work out. The only faults i see are. 1:. The usbc plug cover skills be white so you can see it and maybe it needs to be better at arranging the plug hole. I think that in the rain water will get in. 2:: the on/off button needs to be harder to push or recessed. I know it will get accidentally pushed from time to time.
