This is a great warmer! I like my coffee hot, and most warmers don't do the job to my liking. This one offers a pretty warm setting and a Hot setting, perfect for me. It also is larger than most, so I can use pretty much any cup I want, my old one had to have a small base, which didn't lend to a large capacity cup. It will stay on for 8 hrs, so I don't have to worry about accidentally leaving it on.This is a great warmer, I will be buying a couple more to give as gifts. I highly recommend it!...and it's pretty, too!

It works pretty well for my huuuuuge mug, this mug does not have flat bottom and it is not glass as recommend, but it keeps warm all day! (Remember this thing is to keep water warm, so the water needs to be warm originally, don't use this as a water heater.) (Update: after a few days of using, I found out you could actually use this thing as a heater! As long as you use recommend mug. The one in my picture was too thick and huge to heat up...I tried a glass one, cold water could actually get heated!)

The warmer has nice modern design and works well. It looks good on a desk. Easy to clean with a moist cloth.You must use coffee cup or tea glass with a flat bottom (no bottom with a raised rim). If it's flat, it has full contact to the warmer.An idea for a future version: USB plug. That's much more common now on a desk than an electric outlet.

Sleek and minimal. Doesn't look like counter/desk clutter. This is one I would actually use this at my desk in winter. Be careful not to touch the warmer in the center because the hot setting is definitely hot! This was an unnecessary purchase that I'm glad I made.

The instructions leave out a VERY important part: Hold the button for 10 seconds and it will stop flashing and go solid. Then it is on. :)I love mine. It works great for all of my different mugs, the extra disk to help with the heat distribution is perfect. I also use it to heat up scented waxes in a little jar and left over wax in the bottom of candles!
