Mug Warmer,40W Coffee Mug Warmer for Desk with Temperature Display, 4H Auto Shut Off, 3 Temp Settings & 1-12H Timer, Smart Electric Beverage Warmer for Coffee, Tea, Water, Milk and Coco(Black)

Used a metal mug the first day, ceramic the second day. I didn't burn myself either day, so that's a win in my book. It did a good job of keeping my coffee warm enough and I was able to finish it each time without it getting cold, and 99% of the time without this it always got cold at the end.Has an auto off feature that is default 4 hours, so even if you forget to manually set it you don't really have to worry too much. You can however, manually set the shutoff by first selecting the temp, and then pressing the timer button to the right of it and it has 1 hour to 12 hour settings.There are three temperature settings and there is an LED light that is different for each setting. Low temp is blue, med is purple, high is red. I used the medium setting(purple) each time since I was drinking coffee. Be sure to actually read the instructions because it notes what should and should not be used on the warmer. It's mostly common sense but to avoid any weird problems you should read through at least the notes section.I got the wood look version and I like it. I think this will stand out and still look good on a variety of surfaces. My desk is a little darker than it is, but I still think it matches pretty well. The darker parts of the wood seem to flow pretty well

I use it to keep my coffee hot.

This is my first warmer with adjustable temperatures. So far I'm loving it. The description made it seem like you can change the light colors, but you can't. Not really. The colors are tied to the temperatures, which I really like. Not only do I like that the colors match the temperature range, but I love that the light exists and is done in a very classy way. The light really helps to remind me that it's on. My old one had no lights and I'd often forget that it was on which is not a good thing. I also really like that you can even warm up a large can of soup with this. It doesn't get very hot, just warm, and it takes about 3 hours for an 18oz can (can open, loosely covered, stirring every hour as well), but if you're desperate and don't have the use of any cooking device, it works. The wood look is also very attractive, and the temperature display is easy to read.

I ordered this product as a candle warmer. It has a relatively large surface area and can hold my jar candle fine. I love that I can set it for any number of hours I want and it will turn off automatically. The only thing better would be if it would then come on at the same time the next day for the same amount of time. I am not quite sure what the round black silicone piece is for. The instructions mention covering your mug if you are using it as a coffee mug warmer to help hold the heat in. I'm not sure if that is what it is intended for or possibly a coaster or maybe to cover the hot surface after removing the mug. The instructions do not mention this piece or it's purpose. Overall I am pleased with this for a safe method of heating my candles.

I got this to use as a candle warmer and it worked great! I love that it has a timer so I can set it and sorta forget it. I love trader joes candles but so often they burn unevenly, this lets me get all the scent out of them before they get tossed! I have only used metal candles on this so far, I am not sure if I would use glass without the little coaster.

So I did over an hour long test to see how it handled coffee. This is important, because this is for my wife. She does a lot of work at her computer and she gets caught up and her coffee gets cold. She will constantly reheat her coffee in the microwave. So I poured a fresh cup of coffee and put it on the warmer.The pictures my be out of order, but I picked a location with a clock displayed in the background so you can see the time that passed. I used my food thermometer with bright and easy numbers to read so that you can see after an hour it still kept the coffee somewhat hot.Over a week of use by my wife, she has not had to reheat her coffee once. She is very happy with it and that makes me happy.I think that it would have been more usable if it had a USB c plug connection, but not being an electrician, I do not know if that would be practical.

I've tried many of these coffee cup warmers over the years and have never been able to find one that worked very well. This unit seems to be bucking that trend. The heat surface is large enough for my typically oversized mugs, and the heated part when set on the high level (167°) gets _hot_. So far no issues maintaining temps which is nice because I'm a bit of a slow coffee drinker (like a big cup over the course of a couple hours slow).And LED because why not, everything else on my desk has been LED-ified at this point.

I bought this to use in my office as a coffee mug warmer because sometimes my coffee goes cold before I finish it. However, since I now use an insulated coffee mug I didn’t need the coffee cup warmer. I read in the instructions that it can be used as a candle warmer which made ecstatic. I love candles and the looks of the flame but in my office I don’t feel comfortable having a burning candle. This worked wonderfully! I used the highest temp on the warmer (my picture shows a smaller candle than I normally use) and it worked great. Highly recommend this warmer.
