Excellent Warmer and the Rubber Pad is a very nice extra...
Color: 301 Black
... This really fits my cups perfectly... Just like it was made for these very cups. I wish I had found this one a long time ago and I am considering purchasing another one! Not Sure why they call it a "Coffee Cup Warmer", it would better known as a Beverage Warmer... but either way, it is a great unit and works great. Heat is great, I don't drink coffee, but it works equally well on Tea... This is an Excellent Value for the money.... Not throwing away cold tea and it stays HOT and mostly fresh! I wish I had found this a long time ago, much better than my older units. I will be purchasing another one in the near future! I think this unit is built well and will last a long time and I will... "Coffee Flavor" - No Thanks.... But it works great on HOT TEA! - Excellent Warmer and the Rubber Pad is a very nice extra... (It will help in not getting burned when I accidentally touch the heating surface by mistake! Excellent thought from the designer! You can adjust how hot to keep it and has a digital display to show the Temp that it is keeping the temperature of. I really like this item and I do highly recommend for Hot Tea and Coffee Drinkers, Works great for Hot Chocholate as well!... Doesn't let your drink get cold!

It's exactly what I was looking for!!
Color: 301 Pink, Color: 301 Pink
This one beats all the other mug warmers I researched on Amazon! That circular pad around the mug can come up and it's flat to the edges so I can sit my whole little flat bottom glass pot of tea directly on it and it keeps it hot, and I mean HOT all day! It also has 6 settings. The 130 barely keeps things warm for me but it goes up to 180 degrees! At 180 You can put your completely cold cup of tea that you left out all night and forgot about, turn this thing on and it will reheat your stale tea (that you probably shouldn't be drinking now) back up to pipping hot, steam coming off, you need to blow on it to take a sip levels! (Yes, I know you shouldn't drink tea that you left out all night but I'm just being real). If you want your hot drink to stay actually HOOOT but also have the option for it to be just lukewarm if that's you're thing, then this thing is for you! It also has a timer for shut off which is neat. The $20 spent on this has changed my life haha!

Upgrade from our last one, nice box, easy to read and adjust. Standard plug
Color: 301 Black, Color: 301 Black
One of our old coffee mug warmers finally died and we were looking for a replacement - this is way better than the old one. It comes in a nice printed box - so great for a gift. Standard AC plug and really easy to see button on front. This one shows the temperature and that's handy. It's just the right size for a good sized coffee mug and keeps it warm for hours - if the coffee lasts that long. It's easy to see that it's on so I can turn it off, but it also has auto off if you forget. I'm not really sure what the silicon topper is for, but it sure does look nice. Easy to clean when turned off and I have to say it's pretty professional looking.
It's a 30 watt model so it draws enough energy to keep that coffee warm and can heat up to 180 - that's too hot for my use but I'm sure you can warm something else with it.
Overall: A huge upgrade from our last one. Easier to read, use and clean.

Good mug warmer
Color: 301 Black
I like this mug warmer a lot. You can choose your temp and it keeps my tea very hot. I also like the auto shut off so I don't have the panic of "did I turn it off? My two minor complaints: 1. The rubber pad that comes with it doesn't stay in place and gets very hot. I just don't use it. 2. The controls are very sensitive. There are so many times that I pick up my mug and I change the temp or I change the timer because my finger brushed up against it. But, otherwise, it's a good value for the money.
