I have to give this one star because it says leak-proof and it is not. I put coffee in it, well below the fill line, screwed the top on tightly, turned the mug sideways, shook lightly, and coffee drips fell into my sink — not from the lid, but from a seam in the middle of the mug.
The mug initially seems to have just two parts – the threaded lid top and the base – but the base actually has several parts and they aren’t sealed well. I found this out because when trying to screw on the threaded top, the entire upper section (handle included) rotated slightly. This was not expected. Trying to find the source of the leak, I grasped the handle and pulled, and off popped the black upper part.
As pictured, there is the black upper part of the base (the handle, and where you drink from), and it is seated on top of the silver/black lower area. A very thin rubber gasket sits between the two parts. It is unclear why they didn’t just make a solid base, since this is what leaks, and I imagine you’d also have to clean in there to avoid a gross mug. It may be a product safety thing where they’re afraid of boiling liquid, sealed up, creating an exploding mug, but then why not have the seam be part of the threaded top instead of somewhere separate?
I tried reseating the rubber gasket several times but it never seemed to make a difference; light use always resulted in a drip or two coming out of the seam.
The mug would be useless as a travel mug if it leaked from the lid (and it doesn’t seem to), but it would be, and is, completely useless in general as a mug when it leaks from the seam. It is very similar to those days you get a Starbucks cup with a bad lid that doesn’t totally seal – you can drink from the lid, and coffee goes in your mouth, but a drip or two runs from under the lid, down the side of your cup, and onto fingers or your pants.
I can only imagine this getting worse, since the handle is going to get the most action, either when you grab it or in using the carabiner to attach it to something. Any pressure while the mug’s tipped and you can hear the seal gurgle – drips en route. The gasket is also so thin, and it sits on top of the lower base’s relatively sharp metal lid, that I can’t imagine it lasting very long with repeated pulling off, washing, and putting back on.
Depressing! Lots of good reviews and so I asked for it for a present for my birthday (today :-/). Instead, I poured my coffee from the “leak proof” mug into a regular ceramic coffee mug, sat down, and wrote this.

I really like this mug. I’m a student and wanted a mug I could throw in by backpack and not worry about it leaking, and this is it! It will keep my coffee warm for several hours. The only thing I don’t really like is that the lid can be difficult to remove if the inside is cools while the lid is tight. It only takes a little pressure to seal the lid- any more and it can get stuck (I made this mistake when I first got it- no problems since).
Having had this mug and the Thermos Tumbler w/360 degree lid, I would make the following suggestion: if it has to seal 100%, get the Leak-Proof. If you can deal with losing a couple drops, get the 360. I liked drinking from the 360 better, but it didn’t seal well enough to leave in a backpack. But it wasn’t a big deal if I knocked it over and picked it back up.

I was looking at this mug online last night and got a little obsessed, but I hate buying things online and not knowing how they work. So I went to Gloria Jeans, and they had it! The ladies were so nice–they let me open it up and we even put water in it. It truly is leak proof! I am a student, so to be able to put my drink in my backpack is very convienent. It also comes with a carabiner that attaches to the handle so you can attach it to your purse or back pack and not have to hold it. Another thing: The lid is VERY easy to wash. For people on the go, this mug is definately worth the price! Oh, and it’s cheaper on amazon than at Gloria Jeans = )

Leaks? Not!
This is my 3rd Nissan leak-proof travel thermos. Lost 1 recently so replaced it with this one. I reviewed the first one and this one is just as perfect.

Good mug to keep your java hot
I bought this to replace a Thermos Nissan 14-Ounce Stainless-Steel Insulated Travel Tumbler. The problem is that my coffee would cool off too quickly with this earlier model…

One of the best purchases I’ve ever made!
It is so great to finally have a travel mug that actually keeps my coffee hot. It seals beautifully.

The quest for the holy non-leak grail
I have spent more dollars searching for the perfect adult sippy-cup only to have one tip over in my briefcase and permenantly autograph any paper document for the next 50 years…

Nice and Practical
It is as good as it gets. Truly leak-proof and keeps my tea warm for hours. It also works with cold beverages.

Awesome… wish I’d bought it on Amazon…
So, I’m picking up a couple of pounds of coffee at Boston Beanstock in the North End today, and I notice this mug. I needed one, so I grabbed it off the rack.

Thermos
I had a Nissan Thermos stainless steel carry mug for years and years and loved it. It kept my drinks boiling hot for 8 or so hours!

Makes a great gift!
Excellent mug! Keeps coffee super hot for about 2 hours and hot enough to drink for about 4 hours. I have given this mug as a gift several times, and the recipient always raves…

Great mug, no leaks
I’m very pleased with this mug. The lid is very easily to close and stay closed ensuring no leaks. My coffee stays hot the whole day (work day).
