LOGUIDE LED Light Up Coasters,LED Bottle Lights, Bottle Glorifier,LED Sticker Coaster Discs for Drinks,Flash Cup Coaster Flashing Shots Light (Cool-White)

I was worried about these affecting the bottles ability to stand up but it doesn't affect the bottle at all.Beyond easy to set up and comes with extra batteries.3 setting options and very bright ! Worth the money. Adds a little something special to your bar for a low price

Got these for a party just for fun. At just over $1 per coaster, it was totally worth it. Made the clearer drinks look cool. Also helped to be able to identify who's drink was who's since we set each do a different color or pattern. Even if your drink is darker like beer, it still makes the glass glow a little which is cool. The adhesion is great, just make sure you apply it to a dry glass. I actually reused a few with some double sided tape. Batteries seem to last a while. I haven't had any die on me yet and probably used for up to 8 hours. Even after sitting in storage for a year, all of the ones I used still functioned. Great gift to spice up the party and make your drink unique.

You stick these on bottles or candles, turn them on and they sparkle and look great. Easy to use

These lights are simple yet effective. They work perfectly for what they’re sold to be used for. But, I had another idea and decided to use them in a 3D printing project of mine and they worked flawlessly. Will be buying more.

I’ve used these twice so far so I can’t say I know the battery life but they were totally worth the effect so far! The sticker is super sticky so I think if you keep attaching to clean glasses they should last for at least 10 attachments. The variety of colors is great and turns cocktail time into an LED show. You distinctly see each of the four LEDs and I think ideally the light is diffused over a larger area but I can’t complain for the price!
