Led Cup Coasters Lights for Car Cup Holder Cup Pad with 7 Color Car Accessories Decoration Luminescent Light Blue Bat Pack of 2

They do not stay on one color they fade in an out instead of a solid color.Other than that they work but aren't as bright as I hoped. Ya get what ya pay for for 16$ personally not worth wasting the money

These are sooo cool! At first i was skeptical because when charging they were bright neon green. Then i saw them slowly fade to blue and i was like yay omg! I know this might seem childish but i setup my car interior to be kinda blue or teal so this matches. It would be cool to have butterflies but i love cars and racing and am a tiny 1% tomboy so how cool would it be to have the friggin batsignal in my car at night!!!! So gangsta!!!!!! too bad i tossed out my batgirl costume from two years ago haha. (I got the mask and t-shirt from my sexy vigilante wanna be era. Dont ask(

First things first. I'm Batman. Lol. I love these. 4 stars because, because, because they are micro USB charging. After that they are really pretty neat. They light up. They have my signal! The instructions aren't the best. Follow allong as best as you can. They are pretty simple to operate. Once turned on, they will activate with the weight of your cup/bottle/whatever. I recently received mine with a huge smile on my face! I haven't thought to try them without a full water bottle on tope of them yet to see of they have a stay on function. I will try that. Please drive responsibly and remember, I'm Batman.
