Review on 10 Pack of MUMUXI 20 LED Wine Bottle Lights with Cork, 3.3ft Silver Wire Cork Lights Battery 🍾 Operated Fairy Mini String Lights - Perfect for Liquor Bottles Crafts, Party, Wedding, Halloween, Christmas Decorations in Vibrant Colors by Michelle Lopez

The headlights themselves are fine although I was hoping they would be brighter. Maybe it was the old batteries. Having once forgotten to turn the TV off at night, that pretty much happened to them, so I stocked up on a generous supply of extras and figured out how they can afford to be so generous. They were dead. Thought I might have installed them incorrectly, checked and ruled it out, then pulled out the battery tester and sure enough, right in the red swap zone. I checked a few from each pack and sure enough, dead. I'm going to buy some good ones from Revain, not those off-brand items from China. If Mumuxi sees this and sends me working batteries, I'll double check this review, but in the meantime, beware the buyer!
