VAlinks 2-in-1 Car Cup Cooler Warmer, Auto Car Heating Cooling and Heating Cup Holder, Smart Car Seat for Water Coffee Beverage Milk Warmer Heater Cooler Fits in Commuter / Traveler / Road Tripper / Recreation

the cooler underneath the internal middle of the cup, not maximum operation. it only keeps your ice cup more long time a little bit.

Works great, but, cups and cans usually have a bottom oval ship. This significantly reduced have effective the cooling works. Heating works fine. Although a nice size, but still too big to sit in car cup holder for long.

Doesn't fit in cup holder well and doesn't cool drinks down at all.Heater might work I didn't try it. I only bought this to keep my drinks cold.

Cooling does not work very well but it is great for heating baby bottles on the road. Heats fast. I would recommend this for heating things but not for cooling.

I bought the car cup warmer as gift for my husband who’s a CDL driver. He was always complaining that his coffee was getting cold and was wasting his money on coffee all the time. The cup warmer worked out perfectly for him. Now he buys his coffee at truck stops or even cold drinks and all he does is place it on the warmer/cooler and continue to enjoy his beverage. It has also helped save money, since he finds no need to throw them away because is not hot/cold after few minutes. So the Valinks has worked wonders.

Doesn’t work for cooling, after a fee minutes working was overheated and started warming the can

This thing is really cool. I bought this for when I take road trips, which is not often but it's a couple hours at a time. It is super easy easy to use; you just press a button. I used it for cold but tried it hot just to see if it would work. It worked all right. I love that it changes fast. This would have been super helpful when I had little ones and needed to warm bottles in the car. Highly recommended!

returned it becasue it does not work well
