As with everything, I went on a search of all mug warmers in the universe before buying this one. I found a universal complaint of ALL mug warmer reviewers (of any brand) was "doesn't get hot enough" (especially the USB models). I think the manufacturers walk a thin line between "doesn't get hot enough" and setting the house on fire.

Initially, I tried putting a cold cup of coffee upon my new Mr. Coffee and was disappointed in the warmer's ability to heat up an already cold cup of coffee. (tried both metal and ceramic mug)

The good news is that if you put a fresh hot cup of coffee right from the coffee maker onto the "burner" that it does a pretty good job in keeping it hot from that point. I review this as satisfactory performance and give extra credit for its slim and sleek design.

I bought my Mr. Coffee mug warmer locally at a store. I wasn't expecting much out of it because of the reviews about it here on Amazon, but hey it was really cheap, under ten bucks. I was pleasantly surprised at how it kept my cup of tea consistently very warm throughout the day while I'm at work. This is how hot the heating plate can get: put a drop or two of water on it, and the drops will sizzle and evaporate quickly. The key to getting the best experience out of using the Mr. Coffee mug warmer is to use with a cup of HOT tea/coffee/soup/whatever. It won't make your cold beverage hot again (use a microwave for that).

I've had it for several months now, using it daily, and it's performed very well! Here is the deal with temperatures. If you place a hot cup of tea/coffee on it, it keeps it hot! Not the burn your tongue hot. As you drink, the cup becomes less full, and actually heats the contents more. Also, I've placed a half full cup of cold coffee on it, and it heated it up to a nice warm temperature within a few minutes. The heating plate will accommodate larger coffee mugs. The only disadvantage I've noticed with it is the counter gets rather warm were it is placed, so keep flammables and paper away to be safe. Also it does not have a auto shutoff that I'm aware of, however I have it plugged into a power box with motion control, so if I leave my desk for a long period it will shut off. I also try to make sure the bottom of my mug is dry before setting the cup down on it, to keep the heating plate clean. So if your like me and like sipping on tea or coffee at the office, with out going to refill for a hot cup every time your liquids get cold, then you'll be happy with this warmer.

I don't know why so many people have trouble with this item. My mother-in-law gave this to me well over a month ago and I think it's the greatest thing since TIVO. The key is to use a regular size cup with a flat bottom (not the ginormous ceramic cups that are more like SOUP bowls and only have a tiny bottom), and to put it on the warmer as soon as you pour the coffee into the cup. It WILL keep it not just warm, but HOT. It is 3:30 in the afternoon right now and I am still sipping on a HOT cup of coffee that I poured at 8:00 this morning. The lower the liquid gets, the hotter it gets, so be careful. I've also found that putting a piece of paper over the cup (like a piece of junk mail or an old CD case--without the CD inside, of course) will infinitely increase the heat factor, though it's not too safe and really isn't necessary (I've done it a few times when the dogs were shedding and my husband wanted the ceiling fans on - didn't want dog hair in my cup, so I covered it...and it was so hot I burned my tongue.) Regardless, this item (the Mr. Coffee Mug *WARMER*) is not meant to heat up cold liquids; that's what microwaves were invented for. This is a great product when used properly and at the very least, it does what it was intended to do: keep beverages warm.

This product is perfect. It does exactly what it claims to do...keeps your beverage warm. It won't be boiling hot, but it will be at a drinkable temperature until you are done. The chord is long enough and gives a decent range of use. I like to sip the same cup of coffee for hours while I am working, reading or studying and now I never have to microwave it again. I have noticed that it doesn't do as good of a job when the mug is full, but the end of the cup will be quite hot. Well worth the price.

We've been looking for a cup-warmer that would actually work...the usb-powered type just didn't have enough power, so we returned them to the local store. What really won this particular model is the fact that someone wrote in their review of this product, "...a drop of water on it sizzles." So we gave it a try; sure enough, a drop of water on it sizzles, the coffee stays warm, and we're happy we got it. It works best with flat-bottomed glass/ ceramic cups, but it will also do something for cups/ mugs that have a ridge around the bottom edge. It will work for an 8- to 14-oz. mug, but it works best with the 8-oz.
All that being said, here are a couple of satisfied customers who recommend the product we just acquired.

coffee warmer only keeps coffee lukewarm. so i am still in the market for a coffee warmer.

I was wary about getting this as I kept seeing people say that it only keeps things lukewarm and I prefer my coffee/tea just shy of scalding. However, this product is my new best friend. As long as you start with a cup of something HOT it will stay that way - especially when your drink gets near the bottom. Sometimes if i start with a cup that isn't pipping hot, I just put an old CD case over the top and it will heat up a little more , but its not as good as when you start with something hot. Also, I found if you turn it right before you go fix your coffee, its starts keeping the heat quicker/better. All in all, great product when used as it was created for - maintaining heat, not as a hot plate.

I bought 3 of these and I threw them all away. Your coffee will stay hotter in a thermos than on this warmer. I think a light bulb would do a better job! I wrote to Mr Coffee several times and never even had the courtesy of a reply.

I was expecting this to keep my coffee and other drinks warm BUT it keeps it hot! I have to blow on my coffee or hot chocolate before I take a drink. I can walk away and come back an hour later and it is still hot! I love this thing! I'm sooooo glad I bought this!
