A great travel mug if you're not the driver!

Excellent Thermos brand quality. Truly keeps drinks hot for about 7 hours. If you pour boiling hot liquid in, you will have to wait about 2 hours before you are able to drink it.

Downsides- it is not quite tapered enough, so it is a very snug fit in the cup holder in our 2016 GMC Sierra, and the handle is too long, so it sits tipped  at an angle. The handle also sits at a wide gap away from the mug, so that is a bit awkward. The open/close is difficult to maneuver while driving, as you have to look at it to see if it is marked open or closed, especially with its three-way tab. Would have been better with a single sliding closure.

I had a Thermos King Travel Tumbler and it worked great. It kept my coffee hot all morning but the cap mechanism was a pain to disassemble/ reassemble for cleaning and the gasket eventually gave out after a year and I tossed the tumbler with no interest in buying another one.<a data-hook="product-link-linked" class="a-link-normal" href="/Thermos-Stainless-Steel-King-16-Ounce-Travel-Tumbler-Midnight-Blue/dp/B002PY7AYS/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Thermos Stainless Steel King 16-Ounce Travel Tumbler, Midnight Blue</a>.

I bought a two pack of Contigo auto seal travel mugs to replace the Thermos.<a data-hook="product-link-linked" class="a-link-normal" href="/Contigo-Autoseal-Travel-Mug-Stainless-Steel-Vacuum-Insulated-Tumbler-2-Pack-Blue-Green/dp/B0027SB2Q4/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Contigo Autoseal Travel Mug - Stainless Steel Vacuum Insulated Tumbler - 2 Pack (Blue/Green)</a>&nbsp;They are very easy to clean and I liked the auto seal feature that keeps the mug sealed at all times unless you press a button to sip. But they are not insulated very well and my coffee would already be tepid after 2 to 3 hours. They are so poorly insulated the exterior of the mug would get very warm. So off to the thrift store with those.

I decided to give this Stanley a try. It is very easy to disassemble/reassemble for cleaning and has the same type of auto lock feature I liked about the Contigo.  I always preheat thermal containers with boiling water for at least 5 minutes before filling with coffee about 7am. With the Stanley my coffee is still hot at noon after sipping on it all morning, performing just as well as the Thermos brand mug.

The only disappointment I have with this mug is the finish. The product page picture gives the impression it will be of the classic green hammertone finish that has been on Stanley containers for years. But its not.  It is a much less interesting glossy olive drab paint with a textured finish. If you zoom in on the picture of the Navy color option it is the same finish only olive drab.

I purchased this mug to replace a stainless steel mug at work as I cannot handle the taste of metallic coffee.  It works well for me.  It is a welcomed alternative.  In fact, I just purchased a second one to use at home.  I was hoping this manufacturer would make a tall and skinny model that could be used as a travel mug while in a car.  Maybe that is next?

This travel mug is perfect and it really does keep hot drinks hot for hours.  Never leaks.  When cleaning, there are a few pieces inside the lid that you want to take apart and clean out, but totally worth it for this snazzy mug.  and it does drip a tiny bit sometimes if you leave it on its side, or it tips over in your bag, but overall, this is a great product.  I bought my father one and he loves it too.  I guy I used to work with had one and we would always talk about how great this mug is! wow!  and I totally bought this as an impulse buy b/c it was a deal of the day.  well worth it!

I am a relatively new coffee drinker, so I still sip my coffee.  It can take me a while before I even make a dent in my drink.  I make my coffee at 4:45 am, and by 8, my coffee is STILL drinkable!  It's not "piping" hot at 8, but it is at 7!!  It's an amazing mug.  The only things I could think of that might annoy some, is that it's NOT possible to use only one hand for this mug.  You need one hand to twist it to the "open" position, or you may spill it in the car.  Overall, I HIGHLY recommend this mug.

This is the second of these mugs I have purchased, this one for my mother, who fell in love with mine.

It's important to note off the bat that this is a drinkable Thermos, not a travel mug.  While a travel mug helps keep coffee warm for a period of time, this thermos will keep coffee hot for much, much longer.  I have been known to make coffee and leave the cup at home, only to return at lunch and still have hot coffee!  This actually can be a bit of a problem, as the coffee can take a while to cool until it's drinkable.  I tend to drop an ice cube in the mug before filling it, which makes the coffee the perfect temperature for about 4 hours.  It has a 2 1/2" base, which fits perfectly into my Mazda cup holders.

I have used it for cold drinks as well, and had ice cubes remaining after hours on the road.  The difference in insulation between this and other mugs I have used is incredible.

The greatest advantage of this Thermos is not the great insulation, but the fact that the lid comes apart completely to be cleaned.  Depending on how you take your coffee, this may or may not be an issue.  If you drink black coffee, then rinsing the lid through should be enough.  If you use milk though, residue will build up in the parts of the lid that are hard to get to, and eventually the mug will become uncleanable.  This mug does not suffer that problem, as the lid comes apart fully and all surfaces can be cleaned.  If you read reviews of many otherwise good mugs, you will quickly see this is a huge problem with other designs.

Some have objected to the fact that Thermos recommends against putting their vacuum Thermos in the dishwasher.  This mug takes about 10 seconds to rinse out and wipe dry, and the lids takes a minute or two to clean once a week, otherwise I just rise it as well.  Cannot see the need for the dishwasher, and if you use it daily, you'd never keep up.

I should also say that, while nothing is completely spill proof, I have never had this mug spill, even though it has tipped on its side in a bag full of books or flipped upside down while full of hot coffee.

I use this mug everyday and would readily recommend it to anyone.

At a risk of over simplification, there's three types of travel mugs:
1. The cheap, hard plastic garbage suitable for handful of trips yet ripe with mass spillage. It fits in your cup holder...and that's about it.
2. The slight upgrade with a nice grip and metal elements...but can dribble on occasion. Looks good, is trendy, but visibly falls apart plus leaves coffee stains on your shirt.
3. The trendy, fancy model that's insulated to the max...but can cost an arm and a leg. You wonder why that mug costs 25+ bucks, but it beats the bejeebuz out of 1 and 2...even if all three are made in China.

My friends: take the plunge with #3.

The Thermos Stainless King is - hands down - the best Travel Mug I've ever used. No burning fingers anywhere on the periphery, terrific internal insulation, a ridiculously effective non-spill and clearly marked opening system, plus highest quality materials combine to make this the Travel Mug you wish you always owned. It also looks quite spiffy, proud of being the Porsche of Coffee-to-go transport. (I can't judge the peeling issue in the pics, however, as I haven't had it long enough.)

It's crazy what a difference 10-15 extra dollars makes. The Thermos Stainless King feels durable because it is. Everything about it feels as if a little something extra went into hitting this price point, one I can't help but suggest versus multiple failed attempts at cheaper models.

While this is a Vine Review, it's a product I would gladly purchase 2x over to have additional ones around the house. The other 970+ people got it right: this is an excellent Mug.

This mug works very well. It doesn't spill when it turns over. The only thing is that it keeps my tea and coffee sometimes too hot. So it takes me longer to drink it. It is great for longer trips but maybe not for everyday on the way to work use. I would purchase again. Overall it is a really good item.

It would have been perfect had it had a plug / Stopper for the sip hole of the lid. It's not the best Travel mug because of that. As I drive I have to put my finger on the sip hole so it doesn't splash everywhere.

As a mug, this is great. As a travel mug - it falls very short. It doesn't fit in the car cup holder. If you're looking for something to keep at your desk, this would be great, but I have regular mugs for that. This one was to get me through my morning commute and it just won't work.

I got this mug today, this is a really neat travel mug. It have a really special design, a lock to prevent you open the mug by accidentally in the bag which I like lot. Recommend!

Here is my opinion on this travel mug:

PROS:

 1. The mug will keep drinks hot for an insane period of time. I've had coffee stay hot for 6 hours easily without pre-warming the mug.

 2. When the lid is screwed on right and closed properly the mug is completely leak and spill proof.

 3. The sleek and slender design fits into virtually all vehicle cup holders.

CONS:

 1. Without having a handle or any other marking to reference where the two openings are for the drink to come out of, it is very easy to spill the drink all over yourself and possibly burn yourself.

 2. Having to completely disassemble the lid to clean it properly.

 3. From constantly removing the seals for cleaning the seals begin to stretch.

Overall the mug is fantastic for its superior ability to keeps drinks warm and leak and spill proof. Maybe an indentation in the lid or some sort of marking to reference the drinking points would be greatly appreciated. If not I'd reccommend the mug with the handle.

You will not be disappointed with this travel mug.  It keeps drinks hot for 9 hours and cold for 7!  Not that my drink would ever last that long, but at least it doesn't get cold before I can finish it!

It's taken me a while to discover some of the quirks about my mug, but I'm glad I finally did!

First off, if you want a durable mug that will keep your drink hot for more than 3 hours (comparing with my other travel mugs), get this. I haven't tried this for cold drinks yet, so I can't speak for the other end of the temperature spectrum!

The one thing that irked me that I recently resolved, was how to clean under the sliding part of the lid. Apparently that part just pops off pretty easily if you push on it with a utensil. I close the valve and turn it upside down, then use the end of the handle of a smaller utensil like a teaspoon, to push on the silicone part that covers the mouthpiece. It'll pop right out for easy cleaning, then just click it right back in afterwards!

This detail, I haven't decided yet if it's a good or bad thing, but my co-workers think it's a preferable thing. I find that sometimes if you don't slide the valve back quickly enough, the seal for the air vent in the back, won't uncover and it'll make it hard to drink. However, the fact that there is a seal for the air vent, means that your mug won't leak beyond what liquid might've seeped under the edges of the sliding valve itself.

The one con, also involves the air vent. Make sure you don't put too hot of liquids in your mug and close it! The steam pressure will pop the lid off! What I usually do is I'll leave the sliding cover open when I put the lid on the mug and if it's still hot by the time I need to leave, I'll leave the sliding cover open just a little so that it can vent without the lid popping off. And whatever you do, if you need to mix something hot, just stir it, don't close the lid and shake, cause the lid will pop off then, too! *lol*

So, as you can see, the air vent cover, while a pain in the butt sometimes, is also useful! It's just learning to work with it!

After getting fed up with cheap travel mugs (leaky tops, limited ability to keep coffee hot), I splurged on the Nissan mug several years ago.  Hundreds and hundreds of commutes later, I can't say enough good things about it.  The only days I'm disappointed are the ones I forget my Nissan mug at work and need to make due with a lesser mug.  It is true that the base does not fit in most car drink-holders; not a problem for me, but could be a deal-breaker for some.  Also, I don't use the sipper lid, so I can't speak for that.  But if you're looking for a rugged, leak-proof container to transport your 15.9 oz of java and keep it hot for hours, you won't do much better than this item.

This is travel mug 10 or 12 and exactly what I've been looking for.  Keeps coffee hot for hours, even when the car is parked outside in below freezing temperatures.  Other reviews alluded to the button that seals it not indicating it's position very well, and I do find myself pushing it a few times to figure out if it's open or closed, but that is so minor in the scheme of things.  It also took about a day to get used to 'sipping' out of it, but once I did, I really appreciate it - you would have to work at it to burn yourself.  The one 'modification I made was adding short little lines on the top by the button to orient it - there are two openings for beverage to come out, 180 degrees apart, and if you try and drink at 90 degrees (between the openings) it is kind of awkward.  So.  Not perfect, but still far better than anything else I've tried.  And the drawbacks are minor and easily overcome.

I love this mug like many others.  I use it daily to bring coffee from home to work. It rides around in my commuter bag on the NYC subway and has never leaked.  I did hand wash it for a while but eventually succumbed to laziness and ran it through the dishwasher.  Like many others, after going through the dishwasher a few times I had some chipping and scratching on the paint as a result.  It didn't bother me at first but eventually it bothered me enough that I did something about it.

I used a combination of a wire wheel brush with a 12v cordless drill, old dental pick, 1500 grit automotive sandpaper and a scotch brite pad (green) to remove all of the remaining paint and take it down to a bare brushed stainless steel.  I masked off the thermos logo with painters tape as well.  Now it looks industrial and I don't have to worry about it scratching.  If it does a simple buff with the scotch brite and it's good to go.  I've added a picture of what it looks like with bare stainless.

I took off one star because while it's a tough mug and hasn't leaked on me the gaskets are extremely difficult to clean and deodorize.  I've tried boiling water, vinegar, and denture cleaner.  They all work OK but Thermos should really offer gasket sets or replacement tops.  The bottom is basically indestructible for the average user.
