...but as far as birthday presents go, better late than never right? With that in mind I present to you the USB Coffee Warmer from Chows Industrial (China).
It claims to keep your coffee warmed to a pleasant 40 degrees C, that's 104 degrees, which most people would probably consider lukewarm. To me, it would be tepid.
And, after reading the comments on Gazotto's post, I'm thinking maybe it's not such a great gift idea after all.
