COSORICoffee Mug Warmer & Mug Set for Desk, Cup Heater, Office & Christmas Gifts, 1°F Precise Temperature Control, Touch Tech & LCD Digital Display (77-194℉), 304 Stainless Steel, Silver/Black

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.

Update: After heavy use. This needs a built-in off timer else will stay on indefinitely. I have it hooked to a smart wall timer now. The unusually bulky power adapter is on the plug side, so make room at the outlet. Other than that its a really good unit. I would still recommend.This is probably the best warmer and mug combo I've ever owned for my home office. The warmer is stainless steel and has some weight to it. Unlike the others full plasticky construction. The Digital display is clear and bright. Controls are easy. Best of all the heat setting will go up to 230 degrees (but the liquid in the mug will never reach that obviously - 212 degrees is boiling). Its more to compensate/balance with the ambient air cooling the liquid and the heating element. Realistically, you can get around 180-190 degrees sustained liquid temp....with the LID ON (it helps to insulate the liquid temp).Which leads me to a design suggestion. The mug lid is just a "cover" with no seal to avoid any spillage...and the instructions clearly warn not to drink with the lid on despite the cutout (it's for straw or spoon). It's an inconvenience for sure. Cosori, please add a seal/o-ring on the lid, so it is truly a traveling mug. Other than that, this is the AMAZING. Worth the extra cost. Great holiday gift!

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 thisI 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.
