This mug is the best mug I have ever used for keeping the coffee warm. It's still very warm after lunch. On one occasion I left my coffee in the car for the entire day and when I took a drink it was still warm!

But....The fatal flaw that this mug has it's top. It does not screw on. It has a slip on top secured by a rubber "O" ring. If the top is removed at any time after filling (with coffee) the top will not stay in place. It will actually pop off while it sits on your desk and not over time, almost immediately.

So if you drink one cup of coffee a day and don't need a spill proof mug, this is the best you will find.

This mug deserves 5 stars for its ability to keep liquids hot for a very long time. It is attractive and easy to clean. I was disappointed with my purchase, however, because:
1) The lid is really not leak-proof. It's even an exaggeration to call it leak-resistant. You must carry the mug fully upright if you don't want your coffee to leak out of the top (and onto your clothes, shoes, or the floor).
2) The drinking hole is too small. Because Thermos didn't provide a small opening somewhere else on the lid to mitigate the effects of the vacuum seal, you can only take tiny sips of your drink at any given time. It's virtually impossible to actually *drink* from it. I've resorted to pouring my coffee into a porcelain coffee cup, which defeats the whole purpose of this mug. I would have been better off just buying a true thermos.
3) It doesn't really hold 16 ounces of liquid, especially considering the leakiness of the lid.

Great quality and insulation ability. The lid could spill if tipped over, otherwise the thermos is wonderful. Materials used are very good and handle attachment to mug is secure. My previous Nissan thermos mug lasted me several years until I lost it. I expect this model to last even longer. This mug is easier to clean because there is no lip for dirt to trap. Cleaning it is very simple to perform and finish on the mug is very attractive.

This is a great travel coffee mug. It stays piping hot for hours. The lid vent could use a little work- but over all - its worth the price. Fits most any cup holder & very pleased with our purchase.

My husband got me this mug for a gift a couple of years ago. First, he had to drill a small hole in the cover because the lid kept popping off. That seemed to solve the problem for a while. Then, one day I noticed that one of the areas where the handle was attached to the mug gave way and the next thing you know, the coffee was in my lap! The whole handle fell off! Now, I use it without the handle, but the lid has started popping up again. maybe it's time for another hole or another mug! Oh, it does keep coffee hot for quite a while-that is the best thing I can say about it.

My drive to work each morning is 30 minutes. I was looking for a mug that would reasonably retain a nice warm drinking temperature for the entire commute, and one that was Stainless Steel on the inside.

Dissatisfied with plug-in mugs after trying 5 different ones, because they all failed within 6 months, I resorted to looking for a passive mug.

I ordered a Thermos Nissan from Amazon and while it was in shipment I bought a Starbucks mug for $19.95. (Both are 16oz mugs)

The following review compares the heat retention ability of the Thermos to the Starbucks merely for something to compare the Thermos to as the Starbucks' heat retention ability has proven to be adequate for my commute. I also did a leakage test.

First the Temperature retention:

I heated water to 170 degrees in two identical glass pitchers; then I poured the water into the mugs. Every 10 minutes for 30 minutes I took the temperature of the water in the mugs, opening the lid drink access door, only to check the temperature of the liquid, then quickly closing it.

Time: (after) Thermos Starbucks
Temp (F)
10 minutes 154 151

20 minutes 150 145

30 minutes 143 139

The Thermos won this test; you can decide how relevant the small difference in heat retention is.

Other Considerations:

1. The Thermos has a snap into place lid that fits snug when the mug is cold, but merely adequate when the mug is heated.

2. The mug fits nicely into my Acura TL's drink holder, as I believe it would in most any.

I then subjected the Thermos mug to a "tipped over" test. (Mug is Full)

First: Slowly tipped over as if your hand lightly brushed against it while it was on your desk.

The Thermos leaked at a rate of a tablespoon per 10 seconds while laying on it's side.

Second: Rapidly tipped over as if you quickly reached for the phone at work and hit the mug fairly hard.

The Thermos' lid came off spilling the contents.

Third: For the third test I attempted to lift a full mug by it's lid; simulating retrieval from a deep coffee holder. This test DID NOT take into consideration the friction developed by a drink holders rubber 'grippers' that is installed in most drink holders.

The Thermos' lid came off but not until the mug had actually come off the floor surface I was using; spilling the contents. (Presumably different lids from mug to mug will have different gripping characteristics)

Conclusion: I was pleased with the Thermos' ability to keep my drink hot on my 30 minute drive, but felt the lid wasn't firmly attached enough to be in a car nor on my desk. I additionally felt the lid's rate of leakage when closed, was unacceptable.

I like that it is slim enough to fit in a regular cup holder and the handle is nice and comfortable, but it makes the cup topple over easily.

This item does a fine job of keeping liquids hot or cold; however, the lid easily pops off. If you pick up the cup by the handle and place your thumb on the lid, it will come off. We use the item for cold beverages most of the time. I cannot recommend it for hot liquids without that warning.

Just got this thing for hubby for work...he didn't even get out the door on first use before the lid popped off when he rested his thumb on the top edge! What a shame! He loves his Thermos Work Series 40 oz. thermos as it keeps things very hot for a long time...best he has ever had, but this thing that passes for a travel mug is a disaster for Thermos. I have no doubt that this model gets lots of returns and complaints.

The other thing that worried me was the fact this travel mug is so light! This thing weighs less than a single piece of my 18/10 stainless flatware! It felt more like an aluminum alloy than stainless steel. It doesn't look like stainless on the inside either, but that might just be because it is unpolished. Still, I would've expected some heft to stainless steel and this thing is light as a feather, which means it would be prone to easily tipping as this thing is tall and slender.

Two suggestions to Thermos for improvement would be to change the flimsy rubber seal to a cup-conforming, gripping silicone flange, such as is on my Lang ceramic travel mug...it grips very, very well and in fact I have a little difficulty getting the lid off that one. However, ceramic isn't suitable for hubby's line of work as it would soon be broken. The other is to add some weight to the bottom of the cup to make it more stable.

Hopefully we will have better luck with Thermos' spill-proof model, because this thing is going back!

This mug is really nice. Took it with me on a day trip and it stayed in the hot car for hours. Got home and there was still ice left in the last of my tea. The lid is leak proof too. Very happy with this one and I'm going to order another. Wish it came in a great big 34 oz size. That's a hint for you folks at Thermos-- make a bigger one.
