2-in-1 Smart Car Cup Warmer & Cooler, Auto Car Cooling and Heating Cup Mug Holder, Keep Beverage Cool and Warm Fits in Commuter Road Tripper

Too small to hold common bottled drinks (the most common for me). Although soda bottles can be forced into it, that makes it unwieldly while on the road. Cup really needs to be about 10mm wider. Additionally, it produces a constant rattle while in operation, and there is no way to get into it to repair the loose fan or other components without destroying it. It may be better to choose another similar product.

This drink cooler works very well. I drive a lot for work and always take canned drinks with me so I don't have to stop at a gas station throughout the day. During the summer, my drinks would often get warm before I was half way done with them. This cooler keeps them cold until it's gone. I haven't tried the heating. I don't really drink anything warm however, it does get hot just as quickly as it will get ice cold. The build quality could be a little better, it does feel like cheap plastic however that doesn't effect it's performance at all. If you're in the market for one of these, get it.

You can fit a can of pop in this, and that's pretty much it, and ta-da, you have a really not so fancy, loud ( but not for long because it shuts off right away) pop holder! Yay, NOT! I'd actually put up with all of that if it worked! Even if it just worked for my pop! Sadly, it does not...

As a heater it works okay, but I found it struggled to even keep a moderately sized drink can cool. The fan is also *very* loud.

Kind of disappointed. Only works when car running which is expected. Holder is way small for warm drink. Just ok for cool drink

Works great to keep my cold drinks cool when out on a job site. I keep my soda in the holder and keep it plugged in and after a couple hours my drink is still nice and cool to drink. I've also used it to keep my coffee warm so that I can drink it at a later time and it kept it warm without making it too hot to drink. This is great for travelling or using on a job site.

The media could not be loaded.  This product does not do what is advertised to do it does not cool or heat very noisy
