Don’t waste your money
When I ordered these there were 5 star reviews which I now think were bogus. Since ordering mine and waiting for delivery, the actual buyer reviews posted are all one or two star and I can see why.  They are flimsy and I can’t even get them apart to insert a battery. No instructions on how to insert it either. Stick to manual eyelash curlers and a reputable supplier. You know where you are with those.
