COSORI Coffee Mug Warmer with Mug Set

Finally! A cup of hot coffee! It's been years of drinking luke warm coffee or microwaving or until it tastes burnt and looks like dirt. This warmer keeps it perfectly hot and I love that I can change the temp (although I haven't yet bc I'm still amazed that my coffee is finally hot!). The cord is so long and prevents it from being pulled off a table, love the auto shut off, and it works like a charm. Definitely recommend.

I've been using the Cosori warmer everyday for the last couple months now. The mug and the warmer have both held up well and have worked flawlessly. The warmer is very simple to use: Power On/Off button, and Up and Down arrows to change temperature; Very intuitive to use. The great thing about this warmer is that you can fine-tune your temperature setting to individual degrees! This is clearly a design advantage to other cheaper-priced warmers that only have a few pre-set heat range settings. Plus, the Cosori has a pretty attractive LED display that will show the temperature changing in REAL-TIME; No more having to hover your hand or place your hand on the warming plate to see if it's hot enough. The mug is also really great quality. I love the rubber grip around the body of the mug so I can grab it without using the handle; Definitely insulates your hand from the heat. The only thing to watch out for is if you leave your mug on the plate at a high temperature for too long, it could be too hot for your lips. It never got hot enough to the point that it burned me, but it's not the most comfortable sensation to experience. The elephant in the room is obviously the high price of this: I bought mine for $50. It is by far, one of the more expensive mug warmer sets out there, but considering that this does everything that's advertised, I won't deduct any stars from it; I paid the price I paid, and I got exactly what the Cosori said it was. Plus, the unit as a whole is quite attractive with it's brushed stainless steel housing and the mug is good-looking too. I feel like the fit-and-finish is part of the appeal and why you could justify the higher price compared to competitors. Overall, if you're willing to pay the high price of this warming set, I would definitely recommend it.

I’ve been so stuck on the Mr. Coffee basic mug warmer, for melting and blending and creating my own altnoid (CBD, CBG, CBC, CBN, CBDV, etc) oil infusions & emulsions (“tinctures”), just as well as making concentrates into vapable safe distillates for putting into 510 carts, disposable devices, etc. I formulate so many of these items, that a mug warmer is always on my coffee table, which is somewhat of a hideaway discreet workstation for such. Until recently, I’ve been stuck on the Mr. Coffee mug warmer, despite no digital display or temp control, due to its ability to heat up to an adequate temperature — unlike most “mug warmers” / “candle warmers,” which don’t typically heat to the desired temperature (or have something unnecessary and inconvenient for this application, e.g. “auto-off when removing cup” or “only turns on when cup is detected” — which disrupts the even heating temperature from being maintained). But after trying this I feel like I’ve made a move from an Atari game machine to a PlayStation 5. The technological advancement of this specific mug warmer is so unique, despite being common sense design for a heating plate this size, is worth every penny, and then some. For those who use these items for such indication, and rely on them for such (and I know plenty of people utilize this method for blending their distillates or concentrates to make their own safely transparently composed solutions), this is absolutely the only warmer I’ve found on Amazon (as of Dec 2023) which actually has all of the following desirable boxes checked, all of which are pros: • having no need for auto-detection / no auto-off when weight is removed / no weight required for heating, but instead, just works when turned on, and stays on until turned off, or until an unreasonable amount of time has passed — many hours, for safety precautions. • digital display of precise temperature down to the Fahrenheit degree, and perfect maintenance of that temperature, with such smooth touch-interface that makes it possible to pick the absolute perfect temperature for the compound being melted. • heat that goes up to 230 F, which tops the Mr. Coffee basic mug warmer that previously was all I could find to go above (or reach) 200 F on the surface, reliably. • no separation between heating element and borders of device (albeit borders do not get hot to the point of it being impossible to move from the bottom, if necessary), which means no cracking plastic edge like with Mr. Coffee, which has such little heat resistance on the sides that it results in a fire hazard, which has always been my reason for replacing it — whereas this one will actually last, and is so easy to wipe off (oils often being what can break the Mr. Coffee mug warmer, because it essentially results in a sort of grease heating pad if anything is spilled), making it so easy to wipe off, one smooth surface, no cheap materials whatsoever. Serious quality. • it is so sleek, so easy on the eyes, so streamlined & built in such a seamless way, that it makes me have no reservations when leaving it out on my coffee table, since it doesn’t look like a chemistry lab, nor does it create a mess of any sort. And again, it doesn’t crack on the sides from the heating element, because of the quality materials. It is so trustworthy. • did I mention sturdy design and parts? • this price is insane for the digital display and the degree of heating (going above most all mug warmers, making it ideal for formulating distillates), that I have no regrets — also the included mug can be optionally used, for the same indication of melting and blending distillates — by acting as a double boiler of sorts, if putting water in it and then using a separate container inside the mug — resulting in resistance to overheating as well as (with the cap) the ability to heat small jars / containers much greater safely and evenly by adding a layer of insulation. This just isn’t all included in any other product, and this is ideal for blending, melting down, and safely controlling temperature, while safely utilizing it for the indication mentioned, having no worries about spills, easy to clean, perfect heating temperature customization, no need for weight on it to make it work, literally cannot ask for more. I don’t know how this could be improved, for the manner in which I utilize it, since…I have no issues, whatsoever. In fact I was amazed it was as seamless as it appeared on the product page. Especially for the price. I seriously have no doubts this is going to last a very long time. This is as reliable and customizable as it gets.

I owned one of these for 6 years, 4 months. I'm buying a new one now because now the unit sometimes turns off when I pick up the cup. I used the unit almost every day, sometimes multiple times a day. The unit I bought over 6 years ago could heat up to 230 degrees (Fahrenheit). It seems this new unit will only heat up to 194, but this should be fine. I almost always had the original unit set at 200. At this temperature, my coffee (or whatever) always remained hot. When I got down to about 1/4 cup or less, the coffee got too hot. I could have turned the temperature down; but it was easier to just turn the unit off for a little while and, then, turn it back on. This unit does adjust in 1 degree increments. You can get your beverage exactly at the temperature you want. I think the rubber band around the middle of the cup is great. I don't like using handles. They're uncomfortable and clumsy. With this cup, you can turn it around to have the handle pointing away from you; and you can repeatedly pick the cup up by the rubber band without burning yourself. The metal cup can't be put in a microwave; but I keep a ceramic cup near the microwave that I use to heat refrigerated coffee, then I pour the microwaved coffee into the metal cup. The coffee then stays hot on this unit no matter how many hours it sits there. This unit does not have an automatic shut off function; so, if you leave it on overnight or the like, your coffee may cook down to paste. I accidently do this on rare occasions. It does no harm, except, then, you have to clean off the paste or your coffee has a burnt taste to it. Otherwise, you can use this cup over and over and over... again, without washing it, and your coffee still tastes good.

I love this mug and warmer, they work wonderfully and keep my beverage at the exact temperature that I like it! I enjoy drinking hot tea in the cold of winter but hate that it gets cold too quickly, so I love that you can really dial-in the temperature that you want and that the mug itself does not heat up so much as to burn your lip when you drink from it (although I have found that sometimes when the warmer is still warming up, the cup is a bit hotter and later it cools but the liquid remains hot) - I'm able to keep my tea hot until the last drop, so even when it takes me 45 minutes to finish a cup of tea, I'm still able to enjoy the whole thing. The handle and sleeve are the perfect shape and size for my large hands and the light weight of the mug makes it comfortable to use. I even just bought a second warmer so that I could keep one in my bedroom and one in my office and 2 more mugs so that I could more easily rotate them and clean them less often (they are not recommended for the dishwasher, but I put it in there anyway). There are two negatives - the warmer itself does give off a slight electrical smell, even when it is off and once I noticed that the plate was hot even though the button indicated that it was off and I had not had it on for 24 hours. This is a concern since I'd rather not burn down my house or have my pets accidentally burn themselves, so I just unplug it when I know I won't be around for a few hours, just in case - probably the safest thing to do anyway! I am overall VERY happy with my purchase!

Pros: - Heats up great as long as you use the cup provided. - Stainless Steel, easy to clean and sanitary - Easy to use, literally just 3 buttons, power, temp up and temp down. - Good Size Cup, I make 12oz of coffee every morning and this cup is perfect for it. - Cover with a spoon slot to keep your drink covered from things falling in and keeping the heat in. Cons: - Cup gets hot so be careful - Base is kind of big, so make sure you have room - Heating Surface gets hot and stays hot unless you turn off the base. Best way I found that works for me, is as a heater (kind of like a microwave), not as a leave on all the time to keep warm. Meaning that I turn it off when my coffee is warm enough and turn it back on when I need to heat it. This is the way I found that works best so the cup and coffee doesn't get too hot and I don't burn my lips and I personally have my temp set to max hot because of this. So the coffee will heat up faster to the temp I want and turn if off to cool the cup a bit before drinking again. I am a person that easily gets distracted at work and pulled in so many directions I end up leaving my coffee alone and it gets cold so I don't get to finish it right away. I figured out the way that best works for me instead of having to make consent trips to the microwave, which I don't even have the time to do as well because of meetings and projects I have going on. Being able to heat back up my drink at my desk helps in these situations and instead of having to throw out my coffee because it got cold and I didn't get to reheat it at the end of the day, I can now reheat it at my desk and actually finish it.

Excellent product. I drink tea all day. Mug Warmer keeps the beverage nice n hot. I also use it to keep my dinner warm. Been using Cosori Mug n Warmer for over 10 years. Cant live without it. Had to replace for wire connected to Warmer. And electrical fitting on Warmer, loose. But for ten years service, using it all day, everyday….Like I said, I can’t live without it.

Great item but has one major issue. There is no auto shut-off. It does a great job of keeping my coffee warm and I really like the metal mug. But as someone who is easily distracted, it is too easy to leave this running which I've done a few times now. Just something to keep in mind when purchasing.

A must have for those who generally have long sittings on a table. I really didn't expect that it'd improve my productivity that drastically. Really convenient and super user friendly. The quality of the material used is also best.

super practico! mi jefe feliz, para que su cafe permanezca a buena temperatura y lo sirva directo a en su taza en escritorio

A very nice looking cup and warmer. I’m using the warming plate not only to keep my beverages at the perfect temperature, but also to warm up my bread starter, for melted chocolate etc I wish I bought a set of two, one for the kitchen and one for the bedroom. If you are looking for a thoughtful gift, it comes in a nice box too.

Perfect, meeting expectations.

Great purchase and does exactly what it needs my only complaint is that now i have to buy a UK supported plug because i hate using adapters everywhere! If only the design of the plug would be such that you can swap the plug head with different ones....
