The reviews on QVC are pretty terrible. Anyone who buys these may want to slap some thread seal tape around the head and any of the other parts that come unscrewed. And/or replace or adjust the o-ring. I added the thread tape to my couple i3e EOS lights and have never lost a head. Also I bet they would totally hold up to a 10440… lolnot
I got these, nice gifts as they say, or stashaway lights for glovebox or whatever. Can’t beat the price. They are somewhat bigger than typical 1aaa keychain lights but also pretty bright, like 30 lumens. The suggestion of thread sealing tape sounds good though I hadn’t noticed an issue before. The little round carabiner is ridiculously heavy for it’s size, enough that I wouldn’t want it on my keys. Comes with crappy and maybe leak prone battery. I’d replace that before tucking the light away.
