Love It!
Nice flat bottom coffee mug to use with a warmer. I also like the fact that it has a cover on the bottom so if you aren't using a warmer, you can cover the bottom of the mug to place it on a different surface. I also like the handle. I've been looking for a flat-bottom mug and finally I found one!

An extremely picky review of a coffee mug
This mug sets out to do a very specific job, and it does that specific job pretty darn well. I tested this mug on a standard Mr. Coffee mug warmer and it heats up very well. The actual unscrewed mug bottom is 3" in diameter, 3.25" in diameter as it widens to the plastic. It is not marked dishwasher safe. If you want what it says in the description, you will be pretty happy.I will now be extremely nitpicky.The actual mug arrives to you in three pieces: a gasket-sealed lid with a sliding mouthpiece to open and close it, a plastic converter for using it on a normal table, and the mug itself. You can buy a flat-bottom steel mug as a camping mug for like $9, this being worth $20 is predicated on it looking nicer and having the quality of features those don't have.The lid is very, very secure. Too secure, actually, if you want to remove it on a regular basis, it's going to be a huge pain because it's very very tight. This is a huge boon if you're trying to make your mug heat up fast and high, because it keeps the heat in really well! But if you wanted to, say, use the lid to heat up yesterday's tea and then take it off to drink normally...don't push the lid all the way on. The actual sliding mechanism is fine if a little tight, if you have anything remotely like this it's very similar.The normal table converter works great. It actually suspends the mug about 3/4ths of an inch off the table surface with hollow plastic. It will keep your tabletops very very safe, even if you just heated the mug bottom strongly. However, the actual screwing mechanism is a little confusing. It's normally threaded (turning it clockwise as viewed from the bottom advances the converter into the mug bottom), but it's only about a quarter turn. After that, the tightness of the converter itself means you have to *pull* it down and off. The fact that it's normally threaded but upside down compared to your point of view as a person sitting in the chair makes it a little confusing, especially if you don't know to pull. And if the mug is hot and has a liquid in it, don't try to take it off -- that amount of force will get you a nasty splash.The main mug itself is very, very light -- it *feels* cheap. It's for good reasons, but it doesn't have the weight of a premium product. It's essentially a thin foodsafe steel mugbody with a plastic sheath and handle permanently mounted around it. This sounds cheap, but it's good design: the thin steel doesn't build up a ton of heat, the plastic keeps your hand safe from hot steel. One reviewer notes that the steel rim gave them burns on the mouth and I haven't had that experience at all, I think they were just impatient and tried to drink boiling hot coffee. The faux woodgrain is printed with a pretty good amount of detail -- you have to really smash your face up to the mug to see the fuzziness of the image. My only actual complaint about the mugbody is that handle is reaaally wide, about 33% wider than a normal mug, and also not rounded very much. This is very mitigated by how light the mug is and the softer plastic material not really biting into your skin.My biggest fear going forward with this mug is that one day I'm going to have to pull to get the lid off and I'm going to snap the handle. It's plenty strong enough to handle normal use, but you have to really yank on that lid to pull it off. If you are trying to separate it, don't pull by the handle, pull by the body. You'll have less grip but that's better than the handle shearing off. Plastic gets more brittle over time, I don't expect this to be any different.In a perfect world, I would like the metal of the mug to be a little thicker (to provide some heft), the handle to have a steel core (to provide some strength), and the lid and bottom to be a little less tight (so I can more freely change them). I think the latter two issues will go away with use.SO, do I think it's worth the extra $11 compared to a camper mug, and worth $20 overall? Yes, actually. The wood-on-steel look looks very nice, and a lot of the concessions camper mugs have to make aren't present here. $20 is a lot to ask for a thin steel mug, but it's doing such a specific task that I'm OK with it. You will presumably only need one of these mugs anyway, and unlike an Ember mug it won't break in 6 months from water damage or a software update!

Tight lid and take cap off the bottom before putting it on a cup warmer. Happy with it.
Overall very happy with this cup. The lid is a little tight but that's okay as it will be used a lot and will be easier over time. At least that is my experience with container with this kind of lid. I like the cap on the bottom and with a slight twist it comes off easy. I seen a comment with 1 star about the burnt bottom of the mug. Just remember the cap has to be taken off the bottom if you want to put in on a cup warmer like I do. I did like the metal contact with my warmer as it keep my drink nice and warm instead of slowly going cold with out it. It was great for what I wanted. It was packaged very well. I would but it again.
