COSORICoffee 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

I needed cups for my coffee hotplate/warmer. My ceramic Oregon Ducks cup is too thick to conduct and maintain sufficient heat to keep my coffee hot at 140 degrees F. However, the Cosori aluminum cup does a great job. The cups are light weight, dishwasher safe, easy to pick up and hold--the handle never gets too hot--and in my view are very attractive. I needed a cup for a 14-oz brew size, but surprisingly the cup can easily hold 15 ounces. One quick caveat: The bottom is very hot, so, as many people tend to do, don't rest the cup bottom in the palm of your hand. And yes, I am speaking from experience.

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 bought the Cosori two pack and have been using them for a few months now with my three temperature coffee cup heating unit. Typically I use the cup heater on the lowest setting.Things I Like: Although I almost always use the handle, the few times I have picked the cup up by the middle, I appreciated the rubber sleeve providing thermal protection and great grip. The rubber has not deformed under constant heat exposure. I like the top to prevent steam escaping which helps to prevent the coffee from becoming bitter as the volume decreases.Things I Don't Like: The top has a hole in it for a spoon to stick out. I would never leave a spoon in the cup where it could become hot or stick me in the eye if take a drink while looking at the computer. Just don't think it's needed. Opinion item. The only real gripe is the lip of the cup gets very hot, even when the cup warmer is on the lowest setting. I have to remove the cup from the warmer for a bit so it will cool enough for me to take a drink without it being very uncomfortable. I don't believe anyone will suffer actual burns, but it is not a comfortable experience. I'm a grown man with weathered lips from years of outside activity, not just sensitive to the heat. Yes! The temperature of the cup warmer, even at the lowest setting has some to do with it. However, the design of the cup, does not allow for a temperature gradient that results in the rim being cooler.Overall: I do recommend, it's a great cup, just beware if you use a cup heater.

Great mugs for any coffee warmers, but I got them as extras for my Cosori heater, which I love!

Ok, yes, they do work nicely for using with a mug warmer. But without the warmer your beverage will go cold faster than with a ceramic cup. The lid serves no real purpose, except to hinder how much you can drink. I had to stop using it because the rim of the cup was hot and kept burning my lower lip. And yeah, you could say that's caused by the warmer being too hot. But I now use a flat bottomed ceramic mug with my warmer that doesn't burn my lip. So the metal on these mugs is absolutely not right for using with a warmer. Maybe they're good for cold drinks. Really, they're just new JUNK to clutter my kitchen.

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.

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.
