Review on Norpro Cup Warmer with Decorative Design by Denise Diaz

I have two brands of cup warmers, Norpro and Mr. Kaffee. Norpro costs twice as much but is well worth it in the long run because: 1. The finish on my first Norpro from 2014 is still solid, while Mr. Kaffee started to fail after a year and so does their coffee maker, although the heat isn't affected and will be happy to replace them both within the warranty period. 2. Norpro feels warmer than Mr. Coffee. 3. Norpro is a bit more stylish, looks like glazed china and the on/off switch is separate from the plate itself. Both cup warmers use electrical outlets and I don't see the point of USB plugs interfering with powering your computer. I keep my mug warmers on timers that turn off after four hours in case I forget.
