I almost got a USB drink cooler, but now I'm glad that I waited. This heats up, too, and it's cheaper.
I love this. It's a warmer and a cooler in one. I am always hurrying up my tea drinking because I HATE cold tea. But hurry no more with this handy warming device. No more trips to the microwave, either. I seriously could use this, a lot.
My boss is notoriously buying coffee and sipping on it's tell it's cold. Eventually he'll wander over to the microwave and give it a pick-me-up. Frankly, I think this could solve all of his problems.
