2 pieces Universal Car Styling Solar Power Energy LED Car Interior Decoration Light Cup Coaster Mat Accessories for All Cars,Blue

This quit working a month after buying them could not return since it was past the 30 days. Don't waste your money on these. I charged them by the sub cord and the solar panels they won't stay on.

They give off nice light in the dark. One coaster seems to be defective though. Doesn't stay on - blinks on and off - even when fully charged.

These were not the best they died after 3 weeks of use but when they did work they were pretty cool.

Excellent option for having light when at night you can't find the cup holder. Also excellent is the intensity of the light not too strong not too low

They only light up when its dark even if you don't set a drink down on top of it. I love mine!

loved it for about a week, then one of themstopped working.. won't charge fromthe sun or when i plug it in. then another another 1.5-2 weeks later same thing happened. what a waste of money smh

Cool idea. Impressive tech. I only wish the company made red leds.Update: Ordered second set, one was dead on arrival.Needs quality control.

not working well, I charged them on the car dashboard but one of them worked for only one day and stopped
