COSORI Mug Warmer & Coffee Cup Warmer for Desk, Digital Temp Control (from 77°F–230°F), LED Display, Waterproof Design, Coffee Gift

Yes, you are going to pay a bit more. For me, so far, it is worth the extra cost. I have only had the unit for about 10 days, so will have to see what kind of longevity it has. There is almost nothing to not like about this unit. It has a nice heft to it with a brushed chrome metal case. Cannot tell if the bottom is metal (black) but it looks like it. The bottom is well ventilated with holes and sits off the surface to allow air flow. Others I've had were plastic except for the heater. Others have eventually burned out. The last one I had burned out after I accidentally placed a package of buns on it while it was still on. The plastic on the buns and most of the heater case melted severely so I felt pretty lucky I didn't start a fire. With a metal case that should be less of a problem. I LOVE the controls. The digital temp display and the temp up/down arrow controls are cool but not particularly useful. It doesn't take very long to hit it's max temp of 230 F; you can watch it happen. The touch controls (not buttons or something you press) are nicely modern. The on/off button is right there in front. Other units I've owned, had a slider on/off, on the back that took some effort to slide. So far, I could not be more pleased and would highly recommend. Two very minor complaints: I wish the heating plate was slightly recessed. I am used to using my cup, on the plate, closer to me. Now the cup just slides off if I pull it. My biggest complaint is that the on/off symbol is white when the unit is on and RED when off. Red does not mean off to me. My glass stove has an indicator on the control panel that is lit RED when an element is still hot; i.e., red means danger. My preference would be that the control panel not be lit at all when the unit is off. I would like there to be an over temp shut off, and maybe there is, but I just don't know.UPDATE: I went back and read other reviews. Two things others have mentioned are worth of note. First, the whole case around the hotplate does get very hot.(not the controls which seem to be embedded in glass). Since I never have had a reason to touch these areas, I had not noticed. As mentioned, this probably means that the stuff inside the unit is also getting very hot. Whether this will impact longevity remains to be seen. Secondly, I decided to check the temperature of the table surface under the unit after it has been operating for a while. As I said initially, the bottom of the unit is very well ventalated with holes and the unit sits about 3/16ths of an inch above the table on rubber feet. It turns out that the table surface under the unit does get quite warm. Not so you could not leave your hand on it but just hot enough to make you wonder what kind of damage could be done over time. So far there is no evident change in my wood table's surface, but I am considering finding some higher legs to minimize this support surface heating. I have to note that I never checked for or noticed this support surface heating with the other units I have owned.I do want to again emphasize how effective this unit is in keeping my coffee warm. I always have used ceramic cups (not mugs). They have a raised outer ring on the bottom that keeps most of the bottom surface off the heater; only the raised ring is in contact. This unit keeps that last half cup of coffee very warm (not hot) and still pleasant to drink. The two other units I have owned did not perform as well. You may need to experiment with different cups to find ones that perform well with this kind of heater.

this product is just great! easy to use. automatically keeps the temp i set. coffee stays just how i like it, steaming hot, sippable. i start with hot coffee (microwaved or coffee maker), put it on the warmer, turn on the warmer. it remembers my temp setting and sets off towards heating. though it takes a couple min to heat up, my coffee stays steaming hot. i just ordered a second warmer.mug must be flat bottom. none in my house are, so i bought the cosori two-pack of mugs. that's a must. they're steel, which is safe, gets hot, and can't microwave. about two cups volume, 16 oz, half-liter to tip top. i fill it about 1.5cups or 12 oz. , 3/4 full.small glass teapot works great, too.i use the lid. just a lid would help somewhat.reading reviews of similar products all the major complaints do NOT apply here; e.g., it can heat up my coffee from room temp, just takes a while, not my recommended use, but works; my coffee doesn't cool down over time; etc.a suggested feature to add: timeout, to shut it down if i walk away and forget about it. i use an electrical countdown timer where i plug it in, links below.one review here claimed that it took 15min to warm up, got too hot to the touch. she's setting it to 230, the listed max. that's her problem. it's too high for drinkable coffee, almost boiling, unsafe. also, in general, i'd suggest not using any product all the way to its extreme limit. they generally don't do well.i tried some crude temp measurements. most of you can ignore this and just use the display. using my instant-read food thermometer, when set to 184 F , i measure the surface of the warmer about 164 and the temp of the coffee (which matches the temp of the steel) about 154. the thermometer has a thin tube probe, good for piercing a roast, but doesn't get a lot of contact with the warmer's surface, so doesn't get the full heat flow and hence probably reads low and slowly so. the thermometer should be fine for the coffee. the fact that it's lower than the warmer surface is a natural result of heat transfer. so i set mine to 184 and think of it as 184 'cause that's easier than measuring it. as long as i get the heat i want, i'm happy.fyi, links:thermometer: https://www.amazon.com/gp/product/B073L4R283/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1countdown timers for safety:one: https://www.amazon.com/gp/product/B01KKOJ42U/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1two: https://www.amazon.com/gp/product/B01D3QEK4E/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

I purchased an Ember mug last year ($230) and it lasted less than a year before the battery was worn out. I purchased a competitors warming plate (only slightly cheaper than Cosori) and it was OK but I found with the two settings my coffee was too hot or too cool as the day went on. I then purchased the Cosori mugs. I read some reviews from clients that had a less than 5-star experience with Cosori and was very impressed with their responses and efforts to resolve. I decided to purchase the Cosori heating element and it was a perfect decision. Combined with their mugs, I can set the temperature to a level where it is hot throughout the day but not too hot. Far better (and more economical) choice for those who want their coffee hot all day long. I highly recommend this product and have no complaints.

For $66.50 Canadian dollars, I can buy three Mr. Coffee mug warmers. But I'm a sucker for anything aesthetically pleasing. I put it off for months before I finally succumbed to my vanity. So here's my experience with Cosori mug warmer: First time I used it, I turned it on and then I put a mug filled with hot liquid on the warmer. I waited as I watched the temperature rose up to my set temperature (110 C). To my horror, it stopped rising at 78 C. I took the mug off the hot plate, and the temperature began to rise again. I put the mug back on the hot plate, it stopped again (the temperature went up/down a couple of degrees intermittently). I emailed Corsori Support Team, and they said it sounded like a defect. They even started to process a return for me. Unfortunately, they later said MCI Goods is NOT the official distributor of Cosori Coffee Mug Warmer that, they could not process my return anymore. That's kinda suck! Anyways, I gave the mug warmer another try the next day. This time, I let the mug warmer heat up to my desired temperature (110 C) before I put the mug on the hot plate. My drink was relatively hot (~58-60 C) until the last drop. The heat plate took almost 10 minutes to get up to 110 C, so turn it on before you make your coffee or tea. I don't know if I got a defective product but it seems to work.

I bought this unit because I’ve bought other Cosori products and have been very satisfied. This unit is the second generation cup warmer from Cosori. I like it because I can set the temperature in either Celsius or Fahrenheit and it keeps my 16 oz thermal mug hot/warm on pretty much all day.

Product works well, however you pretty much need to buy the COSORI mug that goes with it to get the full benefits of the item. Thermal / doubled-walled mugs do not work well at all and neither do ceramic ones. I've also found that in order to keep your drink at a high temperature, you need a lid. Also, the more of your drink you consume, the harder it is to keep the remaining liquid warm.

No me gustó la calidad del teflón que traé, es de muy baja calidad, sólo he puesto mi taza sobre la cubierta de teflón y ya se está desprendiendo parte del teflón.
