Summary: Totally awesome - this is not hyperbole
Comment: I am, literally, in awe everytime I use this mug. I put hot water and tea in at 7:15 am and close it. I open it at 10:15 and it's still hot...not like "oh so so" hot, but "OH SO SO HOT".
Also, if you stick it in the freezer for a few minutes and then fill it with ice cold (liquor), you can have a frosty cocktail in the parking lot of your favorite concert, even if it's a few hours away. 8) don't forget the chaser. No ice necessary.
I take this mug hiking, climbing, to the club, to work, hell I even bathe with it on occasion.
5 stars A+++, if it ever breaks, I'll buy three more.

Summary: Great if you want a thermos
Comment: On the plus side, this keeps liquids hotter than anything I've ever used. If closed tightly it really does not leak.
But closing it isn't the problem. It can form a pretty tight seal and to grasp and turn the very smooth ridge on the top can require dexterity, especially if your hand or the top is wet.
Also, the lip is not flat, but curves up on either side, presumably to facilitate drinking without spilling. But it means you have to be very careful if you want to put anything on top, like an AeroPress. Because it is taller than wide, "mug" and press can tip over if you, as I am, are not exactly awake first thing in the morning. The handle sticks out quite a bit. This is probably fine for a car. But you really can't pack this as easily as you could if there were no handle.
Customer Rating: Summary: Great mug - you realy get what you pay for!!
Comment: We purchased two of these mugs for use in our motorhome. We were tired of all the cheap mugs we had bought or had been given over the years as promotions, and decided to spend the money on what we hoped would be top-quality mugs. I'm happy to say that they were definitely worth the investment!
We were a little unsure of them before we ordered because we really didn't understand how the lids worked. However, they're pretty simple and straightforward. They are a simple screw-in cap that when screwed completely in makes the mug act like a traditional thermos, keeping coffee hot for 4 hours or more, and making the mug spillproof. Turning the cap one quarter to one half turn opens the mug for drinking, and even when open we've found that it keeps the coffee hot for 2-3 hours without any problem.
The mugs are very comfortable to drink from. They fit into any cupholders, have a comfortable feel in your hand, and look pretty cool as well! They also come with a carabiner that lets you clip the mug to packs, etc. for carrying. The quality stainless steel interior is easy to clean and doesn't absorb odors when swithing between coffee and tea or other beverages.
If you want a quality travel mug that does exactly what it claims to do, you don't need to look any further than this top-quality mug. You really do get what you pay for!
