USB Cup Heater - Target - $2.50

Keeps cup at a constant 81°F. Maybe not steaming hot, but for less than 3 bucks, what do you expect?!

Down side: the thing glows with LEDs, which may make it a bit less than work-friendly.

my coffee gets cold to kwik…this may be a nice investment of $2.50 for me

Ok, been using it this afternoon. POS. Returning it next time I’m at Target.

Cliff’s notes: DO NOT BUY. NOT WORTH 10 CENTS UNLESS YOU LIKE GLOWING LIGHTS UNDER YOUR LUKEWARM BEVERAGES.
