Review on ☕ Enhance Your Beverage Experience: welltop Coffee Mug Warmer with Five Temperature Settings (Up to 212℉/100℃) for the Perfect Sip, Auto Shut Off, Ideal for Office/Home Use, Black by Karen Forsey

This heater is excellent! We only use big coffee mugs and another brand warmer that's very popular, you know, with raised sides, yes, this one. Our mugs just don't fit on a real hot plate. Besides, it's not pretty. This device is a bit thicker than I was hoping for and has a larger diameter BUT it is the hottest heater ever. I use level 3 and it keeps my coffee HOT. I found 4 a little hotter than I prefer. And it's GREAT! Because all the other small heating pads hardly leave any traces. Yes, they're a bit slimmer and more streamlined, but this really is a case where function is more important than form. This thing works incredibly well and it's not ugly. Definitely what I was looking for!
