Review on Vintter Car Cup Warmer - Paper Cups & Coffee Mug, Cup Holder Coffee Warmer for Car - Car Accessories by Ben Rodriguez

I'm surprised! It's small and simple, but it works amazingly. A few days ago I had a long trip and drove 9 hours with 2 stops. I bought a cup of coffee from Starbucks and within 2 hours my coffee was perfectly hot and fresh. I bought my second cup of coffee from Dunkin Donuts and the cup was kept warm for about 4 hours. When I got to my final destination I still had some coffee in my cup and it was perfectly hot and fresh. So the heating pad worked almost non-stop for 9 hours without any problems and kept my coffee perfectly hot the whole time. Wonderful!
