Coffee Mug Warmer, KRGMNHR Auto-Shutoff Cup Warmer for Home Office Desk Use, Electric Beverage Warmer Heating Plate for Tea, Water, Cocoa, Milk

I just got this a few days ago so I can’t speak to the longevity. However, so far I am very happy with this mug warmer. I kept leaving my tea around or forgetting to drink it while working and always find my mug partially full with cold tea. I have an old mug warmer at work that works great, but I work from home most of the time so wanted a new one for the house.This warmer is very asthetically pleasing, and works well. I was a little annoyed by the writing on the surface as that wasn’t included in the product photos, but it’s not horrible. I removed the ugly caution sticker on it as it already has a warning on the surface.The warmer has a touch power button on the surface that cycles between hot, warm, and off. I always use hot (red). It does turn itself off after four hours as described, which is a good feature as I’ve found my office mug warmer left on overnight and over the weekend... oops!! The most important part is that it does keep my tea quite hot if left there immediately after brewing it, and if I’ve left it around and it’s cooled, it does slowly heat up just like my old one does (and my old office one is still going strong from circa 2002!!). I haven’t timed it but it seems to heat up a cold cup in maybe 20-40 minutes or so. I also included pics to show the type of mug I’ve been using that it works well with (the orange and blue mugs in the pic are the same style). The bottom is not completely flat but it still heats the mug very well.As long as this holds up I’ll be very happy with it!! I’ve been testing this in the kitchen but plan to use it in the office. I’m contemplating getting another to keep in the kitchen or dining area as well!

I wasn't expecting this little thing to get so hot or keep my coffee hot OR REWARM MY COLD COFFEE! I'm impressed. I put some room temp coffee on it, sent an email & by the time I was done & ready to drink it, it was very warm, like the perfect temp. I put it back down & sent another email & it was too hot, I had to blow it. SHOOK! I need one for every room in my house.

Looks great on my desk and it is easy to clean. It doesn’t quite keep my coffee/tea as hot as I like unless I cover the cup with a lid to hold on the heat.

You don’t know you need a mug warmer until you have one it works so well and it’s cute to boot plus it does shut off after a while so that’s good. If anything happens maybe I’ll update my review but for now it works

A lot of these warmers are too large for my small desk, but this fit so well (just 4-7/8" diameter) I got a second one for my nightstand (keeps the tea warm while I read before bed). Love the rose gold trim color. You do have to "hit" the power/temperature spot pretty strongly. Highest heat keeps coffee piping hot; if you use cream and leave it on a long time at high setting, the cream will form a skin. But that does take a long time LOL. The warmer has "rubber" feet, but a lot of heat comes off the bottom. So use a cork pad or a trivet to prevent table surface damage.

I brought this to keep at my desk at work. I love the sleek look but it doesn't keep my coffee as hot as I'd hope. I do find it works best with metal coffee mugs than with glass.

I bought 3 of these, thinking several people would be using these in a few locations, but when we got them we decided just one place made sense to use it so we put the other two away. Our drinks got cold just as fast as they always did. It turns out that you need a flat bottomed mug for these to work and I’m surprised that more of these reviews aren’t mentioning that since most mugs do not have flat bottoms. I have ONE mug that works with it so the warmer got minimal use and then stopped working after just a few months. I pulled out one of the stashed ones, same use, and it lasted longer but stopped working after a few months. The third one I have used far more minimally over the past year and I decided to use it as a wax warmer instead. It lasted about a year before it stopped working too but that was with very minimal use.

You can easily change to lower heat settings. Keeps coffee as hot as you like!
