COSORI Coffee Mug with Lids Set of 2, Stainless Steel Cups with Heat-resistant Handle & Slip-resistant Sleeve, 17 oz, Best Match w/Mug Warmer, for Coffee,Tea,Water,Cocoa, Milk, C1601-CM, Black & Blue

We bought this for a couple that was celebrating their wedding anniversary. They loved it and use it daily for their coffee to get together in the mornings. I wish we had kept it and given them something else. Now we have to buy a set for ourselves. They do more than you're a simple coffee warmers as with these you set your own temperature to your own liking and it works very well. When drinking warm or hot liquids, I would suggest quickly licking the portion of a cup where you plan on planting your lips and blowing in that area where you just licked it quickly and blowing on it to cool that portion of the cup first! The stainless steel makes it easy to clean. The rubber grommet makes it very comfortable to hold even when the liquid within it is hot and the handle is also insulated. The set temperature is displayed to my liking (or yours) and remains at that setting even when the unit is unplugged until it's next use.

They look good, keeps drinks hot or cold. The insulating rubber band around the body is holding up surprisingly well, even with regular dishwasher cleaning (top rack only).would buy again.

I wanted to take outside full of hot coffee. But watch out. You can burn your lips in the beginning. Nice to hold and well made.

I bought these cups as additions to the one that came with my Cosori warming plate that lives on my desk. I can't say that it actually keeps both coffee and tea at an actual 230 degrees, but it does keep both acceptably warm. I was using both ceramic and coated steel, but the stainless cups, from Cosori, work much better. Also, being taller, they decrease spatter from the coffee maker, too.

Barely 16 ounces fill it to the brim. ( I have upgraded my initial review because despite the erroneous advertising in capacity, it works better with a coffee warmer than any other cup I own.) But be aware that it almost works too well on high settings: the metal rim will burn your lips. No higher than 140 degrees works just fine.

I already have one of these mugs that came with the warmer pad, but I found that even without the warmer pad - these mugs get HOT when your pour coffee into them and STAY hot much longer than a ceramic or glas mug. Like twice as hot, twice as long. You don't even need a warmer! I think the steel absorbs the heat, then gives it back to the coffee over time? The lid helps keep the coffee steam as well.The handle is insulated as well so your hand doesn't get burned, and the wrap is nice, it also gets very warm : ) Oh, and EZ to clean!

I bought this cause of the "flat bottom" in order to heat it on a desk cup warmer. It... kind of works. Kind of.1. The flat bottom is 1/2 flat bottom. The center of the "flat bottom" is raised so only 1/2 the area is in contact.2. The cup has no insulation. If my room is cold and/or the ceiling fan it on the warmer can't keep up with the cooling of the outside of the cup. I have to drape a cloth over it to insulate it so my 20 watt desk warmer can make it warm.3. The "insulating" slip cover seems to be R1 and the plastic is as hot as the outside of the cup.4. The plastic lid.. is warped. The hole where you drink from has caused it to deform (on both cups) so it has about 1/8th inch opening instead of the lid fitting down all the way around. Every time I drink from it, I feel this defect and reminds me again that this is "not" good quality5. It looks good. That's about the only good thing I can say about this. Very disappointed.OH, did I mention it has no insulation? So.. when I make the coffee very warm (after 1/2 hour on the warmer covered with a cloth), when I pick up the cup by either the plastic, OR the metal of the cup, it is at the temperature of the cup warmer. and VERY uncomfortable. To be fair this is probably not anything that can be done for this short of makeing the cup a "vacuum" cup. Then how would the heat from the base get through to warm it? I had better results from a ceramic cup I have been using for last 10 years then this cup. I just was disappointed in how this performed. It's obvious it's designed to look nice, but the performance of a good coffee cup is just NOT there.
