Instructions bit vague. Put the 2 lights on charge but they didn't start flashing to say they were charging until after an hour and being unplugged and plugged in again.
Also thought they were broken after they were apparently fully charged until by mistake we pushed the light for 3 seconds and it switched on. Phew.
Just as bright as the normal battery version but without the waste hopefully. Also come with a decent manufacturer warranty.
Just needs better instructions
