I got one of these Stanley mugs for Christmas (Thanks, WOOT!), and I LOVE it. Why do I love this mug so dang much?
Two words: SPILL PROOF. But there's more. Several of the features other commenters have questioned or criticized are, in fact, reasons I love my mug all the more. I'll address some of these issues now.
- "The drink does not flow quickly!" How fast do you want to chug your coffee? Most people prefer to sip theirs. The lid's delivery system slows the pour and cools the beverage a little to prevent scalding.
- "The mug does not keep coffee at a near boil all day!" Correct. It is a mug, not a vacuum flask (usually called a thermos, which is actually a brand name). A mug is for drinking beverages at a reasonable temperature. A thermos is for long term, insulated storage. If you need to keep a beverage at the same high temperature for hours and hours, Stanley makes some of the best vacuum flasks available.
- "I'm not sure about that handle." I like the handle. It doesn't interfere with my car's cup holders. It's roomy enough that I can fit a gloved hand in it... like a glove. I've never hooked the mug on my belt, but it's nice to know I could -- without spilling. Did I mention the mug's spill proof?
-"Yeah, but is it REALLY spill proof?" Yes. When the lid is twisted shut, the contents will not come out. Only a deliberate act of twisting the lid open will allow contents to pour. Whether you throw it in a bag, jump up and down with it or shake it, the contents inside will stay inside. That being said, remember that if you've been drinking, drops of beverage might remain on the pouring lip.
An important note about maintaining the seal: The bottom of the lid has a plastic ring that can easily come off for cleaning purposes. DO NOT LOSE THE RING! If you lose the ring, you lose the seal, contents spill, and the mug loses value.
I love this mug. I'm in for two more, just in case mine gets lost or stolen.
