Review on Premium Slate 12 oz. THERMOS Stainless Steel Tumbler from the Guardian Collection by Todd Casey

I bought this mug because I needed something to keep my coffee warm when I go to school instead of paper. The cups are just dirty and a shame to be honest. The great thing about this mug is that it keeps my hot coffee hot for a very long time. When I'm done it's still warm, but not normally warm, more on the hot side of warm, for example if there was a spectrum it would be between center (warm) and right (warm) and I usually finish it about an hour and a half after I put the hot coffee on. It's so good my dad even claims he keeps his coffee hot for about FOUR HOURS which is obviously crazy. Also it never leaks like I dropped it once in the hallway and it was so loud and uncomfortable and this boy behind me picked it up and after that I had to walk in front of him for the next minute or so. I wanted to crawl into a ball and fall apart, but you know what? not a drop came out. Wow. The only downside that made me give it four stars instead of five is that it squeaks like hell. now i know it's a silly complaint, but when it's 7am the last thing i want to hear while unscrewing the lid is a squeaking noise. For example, if you run your finger across the glass, I HATE it. but since that coffee mug didn't make many of my awful wee hours that awful, I'll skip this minor inconvenience. i love you Guardian Collection by Thermos 12oz Stainless Steel Travel Mug Blue and I hope we can spend our mornings together for a very long time.
