EXCELLENT
Even better than what I thought these would be. They hold heat and cold ALL day. Literally. My coffee gets poured in at 5am and it's still pretty hot at 5pm and beyond, so, EXCELLENT. Good job. Nice design fits in any cupholder. Maybe a little too loose but not a deal-breaker. Love, Love, Love the ability to CLOSE the mouth and OPEN with a flick of a finger. So many times I've accidentally spilled on blueprints or contracts but not any more (as long as I can remember to close it. lol). But now it may fall over and it is not a crisis. True containment. Keeping it closed when not drinking keeps the heat or cold in even better. I like the Army green one with the tactile grip handle, but midnight blue (almost black) is nice in it's own way with the smooth handle. Wife got the stainless steel version, smooth handle. All good. (Talking to you Thermos guys... I'd like to see a 20-21oz in the same basic design. Maybe a little more of the tactile grip and slightly larger base for stability on slightly sloped surfaces like truck hoods, as long as it still does the cupholder thing. Seems like you still have lots of space to work with. And, hey...! Why all the difficult-to-remove plastic wrapping when you first get it?? My blue one got all scratched up trying to get that obnoxious, useless, wrapping off! That made me cry, figuratively). But, anyway... Definitely recommend!

The Tea hook sold me!
This thermos mug was an easy yes for me — the built-in tea hook is what completely sold me! I love being able to secure my tea bag without it slipping into the mug. On top of that, it’s very well insulated, sturdy, and feels like great quality overall. My hot tea stays warm for several hours, which is exactly what I needed. It doesn’t leak (huge perk!), and the price was perfect compared to other similar products I’ve purchased in the past. Honestly, this was a no-brainer purchase and I’m so appreciative of how well it performs. Highly recommend!

It's Basically Perfect for Carrying Around Your Coffee
I love this thing. I actually bought this for my wife who has a habit of taking regular coffee cups from the kitchen and then sort of balancing them in the cupholder in the car. In all fairness, there's only a spill every 3 or 4 months, but I thought maybe if there was smaller mug like this around she would use it. That didn't happen, because the house mug is fast and requires no thought. Now, I love mugs and I have too many and every so often, I move a bunch into a box and put them in that cupboard over the fridge so things aren't so crowded. But I like really big mugs that hold a lot of coffee. I have a handful of 40 oz mugs that I use even though they technically aren't for hot liquids. Then I have some 32 oz ones and 30 oz ones of different brands, and some 20oz. What I don't have are any 16oz ones like this because I thought that would be too small. For taking all the rest of the coffee left in the pot or for taking down a half day worth of coffee to my home office so I don't have to come back up, it is way too small. But, for keeping the coffee that I'm actively drinking right now, hot. This thing is the bomb. I've got Camelback, Yeti, Coleman, and Hydroflask, and none of them keeps coffee hot as long as this one. Now, that might not be fair since some of them are much bigger, and like a said a few aren't supposed to be for hot. And, I don't know what rating scale they use for "keep hot" but when it comes to hot coffee that still tastes like hot coffee (not warm enough, or kinda warm, but actually hot) this thing wins in both the "left it on my desk" and the "left in the cupholder out in my car while I ran in 'real quick'" scenarios. Unlike my giant ones, this fits comfortably in my hand and fits in the cupholder of every car, not just the ones with expaned size holes. And, not that I care 90% of the time, but if need be, it also doesn't make me look like some coffee drinking weirdo, or heaven forbid, college student drinking their all day frozen frozen frappawhatever. It's also been in and out of my dishwasher dozens of times and still looks just fine. The black paint won't rub off like some of the prettier designs. It has two drawbacks if you want to nitpick. First, for some reason there is no grip on that little silver ring that goes around the lid, so you have to sit there and really work at getting it to loosen unless you have one of those rubber grippy things nearby, in which case it twists right off. Second, it claims leak proof, and I don't doubt it, other than it doesn't necessarily like click or snap into locked position. You have to put some care into getting it right and then I make sure to turn it upside down and test it a bit. Even if you get everything right, the lever to move it to open position is the kind of thing that could be caught on stuff in your bag and twisted just enough to leak. It's not like it would be a common thing, but if you have a big ol Oprey bag that you just keep shoving stuff into like me, I wouldn't trust it. The good news is it fits the dumb side pouch cupholder for that backpack and I would totally trust the lock in that situation, so thumbs up. Theres also a hook in the bottom of the lid that you could hand your tea bag string with. I haven't gotten around to using it (I don't drink tea the same amount) but it's definitely a cool idea. If you are OK with the size (16oz) then this mug is perfect. It keeps drinks hot without being all extra sized bulky and goes where you go. Definately recommend.

Great product
These tumblers are great. I have two, one for coffee and one for soup. I preheat the tumblers and bring coffee and soup to a boil. Prepared around 6:00 AM the coffee is still very hot (careful not to burn my mouth) at 10:00 break time. Soup is still very hot at lunch. Coffee is still very warm at 4:30 for the ride home. These results are in winter months, northern Illinois, sitting in my truck the whole day. Very impressed and pleased with these tumblers. Totally leak proof and indestructible!

Really good, Quality item
I use this thing every day. It keeps coffee hot for 6 hours plus, even on the coldest days. With the lid closed, I have never had a leak. The lid has a bunch of moving parts and nooks & crannies, which makes cleaning a bit of a challenge, but overall, I like it. After about a year of use, I replaced the rubber seals, because they were coffee stained. they were inexpensive, easy to install, and easy to find on Amazon.

Commuter companion
Very nice travel mug. I use it every day and there are no leaks. Very easy to clean - even the lid wipes down easily with a sponge and warm water. Keeps my coffee nice and hot all morning long. A little pricey, but you definitely get what you pay for here - a pretty sturdy mug that should last a good long while. Nice olive color too - reminds me of my old Coleman camping gear from Boy Scout camp.

Best tumbler going!
This is the best tumbler! I have had one for the past several years. I prefer the model with no handle as it's easier to manage when driving. My coffee stays hot for hours; even more so when I close the "sip" area if I set it aside for awhile. Cleaning it is a no brainer and very easy to dissemble the lid when washing. I have it in navy and silver. Both are nice. I hope Thermos never does away with this model. It is by far the best.

Best coffee mug choice on Amazon
Things that I really like about it: 1) keeps my coffee hot for hours 2) slick design fits nicely into my car/truck cup holder 3) easy to clean - can even really disassemble some parts for a deeper clean 4) use for coffee, and acid from coffee doesn't stain the interior of the cup 5) toggle on top which keeps liquid from getting out 6) love the color! One request that I think would make it even better is having a marker line inside that says 'Fill to this level' because I usually hand my mug to the folks in the coffee shop to fill up and they aren't quite sure where to stop.
