What does a petri dish need to grow bacteria? In general terms; heat, moisture and light. So this USB heating device seems like a good idea, but after a few minutes of contemplation - the Heat Me is nothing more than a germ fest.
If one doesn’t clean this off and unplug it after heating their liquid it could get very nasty - makes you wonder why you’d pick this over something more simple [and probably just as effective] as a USB mug warmer.
