 Better than expected October 28, 2008
The reviews I read rated this "cup" highly, but I was suprized when I received it. This is not just a travel mug, it is a thermos bottle in the shape of a mug. Keeps the hot side hot and the cold side cold. I use mine every day. (Espresso is a great color, too!)
 Leak-Proof Travel Mug August 31, 2008
Product is great, keeps my coffee hot enough till I reach my destination; just as advertised. Fits nicely in my vehicle cup holder, hasn't spilled, as long as I've screwed the cover on tight; performs much better than 3 others I've purchased promising the same thing!
Best mug ever! July 17, 2008
I've had many mugs in my days, but this one is the best by far...coffee stays hot for hours!
 It leaks and so it's going back. June 26, 2008

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.
Best coffee mug ever, a thermos, duh? April 22, 2008

Tried a few mugs out there. If you are serious about keeping your hot beverages, hot, and I mean hot, for 4-6 hours, warm through 8, then there is no other mug. Oh yeah, it's spill proof and has flawless pouring for no-spill drinking too. Limp wristers, a caution, if you tighten the lid moderately, the heat creates a suction and the lid tightens even more. This is the way to keep the liquids spill-proof and hot, but you can tighten it less for easier opening.
