Works great for halloween- put them under any glass item to change the color. Bright green giant fish bowl, bright red vase, bright orange plate, etc- these are awesome for table decor and many other things, especially for Halloween. The great part is yoy can change the color of these with a quick click of the bottom (not just RGB like the old days).

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.

Purchase these to light up a bottle of Nuka-Cola quantum that I got from when fallout 4 came out. And to my surprise the batteries do not last very long for these LEDs. They lasted about a day and a half before dimming out completely. Batteries are replaceable and the package does come with plenty of spares. But the build quality is very flimsy. Fun to stick on for something for the evening, but I wouldn't expect it to last much longer than that. Yeah adhesive sticks pretty well to the bottom of your glass provided that the glass is dry like any other adhesive. And to change the lighting color you will have to grab your glass and press it against a flat surface so it can press the button which is located on the top. Since when the adhesive is used to stick to the glass, there was no way of pressing the button again. In my experience. I tried pulling one of them off of the bottom of the glass after it had been stuck on and one of the coasters had cracked in half. Still functioned but appeared to be broken. All in all great value for the quantity you get to have. A decorative coaster for the evening

Great concept, got them for my son for his prime bottles. The material is a felx foam type stuff and it doesn't sit completely flat on the bottom of the bottle so they all fell off shortly after application. Battery life isn't very long. These are great maybe for a party but not long time use

A lot of colors worked as intended
