Carperipher 12V Car Heated Mug Tech Tool Stainless Steel Travel Electric Cup Vacuum Thermos Smart Temperature Control for Heating Water, Coffee, Milk and Tea with Airtight Lid, Auto Charger

Nice size travel mug. It fits well in my car cup holder, Nissan Quest van. It keeps my drinks warm for a quite long time. Easy to use and clean. The heater is a great bonus to this mug.

I've only had it one day, but so far it has far exceeded my expectations!..It heated the water up fast (I used room temp water) and really hot!...It looks inconspicuous, like a regular mug...It's the perfect size to fit in a standard cup holder in a vehicle...It's simple in design and easy to use...I read the other peoples reviews and I don't know why some of our experiences are so vastly different...For me, so far, I love it!.....:)

It is definitely not leak proof. When I tipped it over, it leaked onto the counter. I can use it, but will have to be careful that it doesn't tip over in the car..

This coffee warmer box was in bad shape as it arrived. But the warmer works good. The internal thermostats really speeds up the warming.Chamar

Product as presented but too big for cup holder in car. Just too bulky. Although it has not leaked, lid does not feel secure.

this mug works great but only works for two months😔😔

Heats water very hot.

Excellent product
