Fast shipping. I bought it when it was on sale on the other day. I had it delivered for my fiance. She has no clue. When she got the package with her name on it, she asked me about it. I first asked her to give me her drink bottle then I turned the light off in living room except the TV. I took a led coaster and pushed its button -- I assumed without reading a direction, too lazy at that moment. The coaster lighted up under her bottle and she immediately loves it. She won't stop staring at it for a while.I'd highly recommended these coasters if anyone wants to use it for drinking at home, at bar, in car, maybe bathroom--holy crap that's an awesome idea, I will try this with hand sanitizer. Ok, I'm going off. Have an awesome day/night!

These are very cool! I purchased these to put in my car drink holders and they are actually made to stick to the bottom of a glass so, My only wish is that they would be clear instead of white as they don't show up really great in my car as I stuck them to drink holders upside down. Otherwise they work great, shipped quickly and are really cool on the bottom of glass and water bottles!

Bought these for NYE to add a little fun to the bar area, when i received them more than half did not work as the batteries were dead and the extra batteries (only able to replace 4 of the coasters) that came did not last more than 3 hours. They also were not very bright and unless you had clear liquid would you even know they were there. i ended up buying new batteries and spent more on those than these but will not continue to use them.

I bought these to add flare to my tumbler and other liquor bottles at a party, These were a hit! Great quality for a fun Item! They are bright and have multiple settings for different light patterns and colors.

3 out of 12 would not light up or flash

These are cool for parties! They do need attached (they are stickers). Good for displaying wine bottles for a party or something. They work best on a light colored/white wine bottle (not bright enough for a dark bottle).

These coasters are a cute addition to any party. Stick them on, light them up and enjoy. Comes with additional batteries. More batteries can be purchased through Amazon. CR 1220

Not what I expected. Very small, they are completely covered up with a bottle of water. Out of the 12 only 3 were working out of the box. To be fair they did include extra batteries in the box which I have not replaced yet. Also they do look pretty cool at night with a clear water bottle sitting on them. They would make a great night light except the battery was dead by morning.
