JiangJing Led Car Cup Holder Mat Pad Waterproof Bottle Drinks Coaster Built-in Vibration Automatically Turn On at Dark Universal 7-Color Light 2-Packs For Tesla

Total waste of money! One of the two failed to work right out the box...just a feeble flicker even after an overnight charge! They don’t secure to the bottom surface of the cup holder reservoir, sliding around, making them an annoying and potentially dangerous distraction to the driver. After less than two months, neither works and they both look like road kill! Don’t waste your money!

Cheap and only one works. The other one work sporadically and the glue is coming off of it already. They are also very thick and I would not even put the in the cup holder because I would be afraid the drink would fall. Also want to mention I can only get them to be green and blue. Not all the colors shown in the pictures.

I gave it 2 stars because technically it does what it says. Problem is you need to be off roading in a Jeep for then to stay on. One is always out and it's always flashing. I drive a mustang with aftermarket exhaust so you know the car vibrates and rumbles and they are still constantly going out. I would not recommend these.

The photos show the units glowing under a water bottle. This does not work. I tried a water bottle filled with lemonade, and one with water and the units would not light up for either. After I covered the bottom of the water bottle with tape, it then worked. They apparently require a solid , not translucent bottom to function. They did not work for two weeks either. Not even a week. Since they react to vibration in the vehicle they come off an on often.

Bought these as stocking stuffers for my husband. He loved them! Charged them right away to get them in his car. The color of the lights change on their own rotation. So far so good.

Horrible quality (backing fell off) with several large scratches too boot. Was planning on returning for refund but missed 30 day window. Will probably use as one- and-done throw away coasters for 4th of July.

Over look the price (not bad) still a waste of your time. Did the setup and the color setting but i was still a waste of time. Recharged every day for 4 days now its just that thing in the bottom of my cup holder.

When i order i saw different reviews, once I brought it bad reviews, is not worthy, it doesn't work ,it say with go on with car vibration or the little bottom in the back but it doesn't go on n I press the 3 sec n more but that bottom is not clicking 😒😒😒,the fact DOESN'T WORK.

Funcionan bien como descrito en la información !
