KitchekShop Coffee Mug Warmer - Fastest Heating & Highest Temperature, Coffee Cup Warmer for Desk Auto Shut Off, 4 Temp Settings & 1-12H Timer, Smart Electric Beverage Warmer for Coffee, Tea (Black)

I’ve now bought two of these. They work very well and I’m happy with them; they really do keep my coffee hot for the duration I select. The heating surface is wide enough, without a raised border, that you could put a bowl or plate of food on it to keep warm too. The 185-degree setting is sufficient to bring lukewarm liquid to high heat in a reasonably short period of time, even though it’s not designed to heat up liquids. A microwave is preferable for that. And to state the obvious, it’s not compatible with Yeti-type coated metal mugs. One caveat: if you have pets who walk on your tables as I do, they can easily turn on the warmer and it can get very hot. Only an extremely light touch is required to activate it. For this reason I unplug it when not in use, which is a hassle but keeps my babies safe.

Best coffee warmer ive had. It keeps it HOT all day. STOVE TOP HOT. Love that is work so well and has huge heating pad. Would fit any mug. No more mircowave for me.

I bought this for my husband because his coffee was always getting cold. He absolutely loves it. He doesn't have to drink cold coffee anymore. You can set the temperature - there's four choices: 131, 145, 167, or 185 degrees. There's also a timer you can set. He's been using it for close to a year now, and it's working just fine. He uses it every day for about five hours a day - even on the weekends. It's about 1-1/4 inches high and 6-1/2" (front to back) x 5-1/4" side to side. It's a sleek, black, and looks nice on his desk. This is great for anyone that wants to keep their hot beverage hot. It's also makes a great gift. Update: adding 2 photos. I was asked to answer a few questions, but my responses don't get attached to the review, so I'm adding that here as follows: 1) The warmer does not appear to be UL certified. There is no sticker or label on the warmer or cord indicating UL certification (or listing, as per the question). 2) Unsure if product contains PTFE or Teflon. There is nothing on it indicating a yes or a no to either, and I no longer have the box to look at. 3) Unsure of where it's made. Nothing on the warmer mentions it, and as stated above, I no longer have the box. 4) Yes, it makes a great gift for any occasion. 5) It came in a box which made it easy to wrap for Christmas. 6) This question disappeared while I was answering another question, so I'll put the question and the answer: "How do I turn it off? Do I have to use the timer?" (I took that as being asked if you had to use the timer and wait for the timer to finish to go off.) There is a power button. The photo shows my finger pointing to the power (on/off) button. The other photo shows the bottom of the warmer and the sticker with some info on it.

Very sturdy, heats up quickly and keeps my coffee warm all day.

I've had this for 2 years now, still going strong works very well and is sturdy. I use it to keep soup warm coffee warm and anything else I want warm. The multiple temps are good for whatever you really need.

Very nice works real good keeps your coffee warm

It heats coffee to temperature selected. It is easy to use in many places -- kitchen islands with eating area and desks in an office-- so any cup you use holds the coffee hot until the cup is empty. I have a warmer in my home in Georgia and my home in Florida. No need to use an app, a phone , just regulate it with an on off switch and a temperature select button. I love it!!

Works very well. My home office is chilly, which meant running to reheat my coffee every 20 minutes. Now I use this warmer set on the 145 degree setting and every sip is hot! I unplug this after I’m done using it because the buttons are so sensitive that they could get turned on without me noticing, or by the cat poking around my desk. I like the auto shutoff safety feature. The cord is plenty long enough to reach the wall outlet. It’s lightweight and looks unobtrusive on the desk. This would be a valuable gift for anyone with a home office, workspace, or readers to keep their drinks warm without interrupting their vibe. I may get another one for my morning reading nook.
