4 Pcs LED Car Cup Holders Light with 7 Colors Changing USB Charging Mat LED Waterproof Cup Holder Interior Atmosphere Light Lamp Decorations with USB Cables for Car Truck Vehicle Accessories

These coasters are great! We have a GMC Acadia and it has red accent lighting inside, but at night it was difficult to find the cup holders due to low light. Not anymore! These LED coasters were the perfect addition! Very cool looking and functional as well! Now, if I can keep my daughter from playing with them all the time we'll be able to actually use them!

Unfortunately the battery life is very short, movement sensor don't work and stay on all the time until battery runs out.

The choice of colors is nice and they are easy to recharge. The lighting effect is pretty cool. The battery charge doesn’t last for longer than a week. The product tends to stick to the bottom of damp cups.

Such a nice touch! They do run out of charge quickly but once you find a charging routine and rotate them out it's no big deal.

All you do is charge them up set which color you want and forget them till time to recharge them the battery life is good. They go off when they are not moving. Worth the price!

The idea of these is great. The execution, not so great. The purpose is to see the light glow from the cup holder to create an ambiance. You can't see the light at all. The cup doesn't allow the light to come through. They only light up when there is a cup in the cup holder.I'm not at all happy with this purchase. Not at all worth the money, and I bought two sets of 4 as I have 8 cup holders in my car.

Very convenient at night

I purchased these because I thought they’d be fun for the kids in the car. Upon arrival, I open the box to find the coasters just laying in the box along with the charger, the other two coasters or in a bag as they should’ve been. Once I charged all four coasters, only two of the four even worked, I have a feeling I was sent used products that were used/returned, which is what I ultimately did.
