Review: Convenient, easy to clean, spill resistant - I love this mug. It's insulated, but it's fairly thin insulation. This keeps it from being too bulky, but it still manages to keep my coffee hot enough- I don't need my coffee to be scalding hot though. It's stainless steel inside so it's easy to clean but there's a coating on the outside so it doesn't feel like drinking out of a metal mug (I don't like drinking from metal mugs). It also feels very nice in the hand and doesn't get too hot on the outside. I had a previous version of this mug that didn't have the close-able cover on the lid, and if I took it in my car when full, some coffee would splash out. The addition of the sliding cover fixes this issue, and is the main reason I replaced my old one. If you tip it over, coffee will slowly leak out but if you stand it back up quickly enough you might not have any spill out. The lid doesn't screw on so it's just a gasket/friction fit but it's quite secure. I don't think it will come off accidentally, unless you do something extremely violent like dropping on the floor. There's very few parts and pieces so it's relatively easy to clean.
Review: Best travel mug I’ve had - This is a great mug. Keeps things hot for hours. My dad borrowed mine once and I missed it so much, my other travel mugs just don’t compare. Finally got it back and he liked mine so much he got two for himself (this size and the 12oz). One of his is blue (mine’s black) and I really like that color. May have to get another.
