I used our wine bottle lights in various liquor bottles and had them setting in interesting places in the backyard. I was concerned about battery life and the Texas heat. So far they're still working and they're great looking in groupings.already of the 5 I set up, 2 don't work. I don't know if they came with dead batteries, or are defective in some other way. Other than that, they look great in different wine bottles for entertaining on our patioDidn't like dead batteries right out of the gate!The few that worked are very pretty, but Gramma MeMe wasn't really happy with a lot of them not working..fresh out of the package. No remote control!!!This product was inserted in wine bottles and made beautiful center pieces for our fund raiser for kids bThey are fine for about a week. I wasn’t very happy because even after getting 2 packs of these, at 3 in the pack didn’t work at all. I will say that the seller sent a replacement.Update: there were lights in the replacement that didn’t work. I told the seller but the seller still charged me for them. Not good business.Jars they suck
