That's a nice cup! I'm not a metal cup fan though. I have used Tervis cups for many years. Awesome high quality cups, but no where near as insulated I'm sure.
The Yeti Rambler is ridiculously awesome - There is no comparison. Everyone has purchased or received some type of insulated thermos - most are cheap and keep things cool/hot for only a few hours (if that). My Rambler can keep ice solid in hot Texas vehicle heat all day. My 30-ounce cost $50 but it will be the last personal thermos that you ever buy...except when you get the itch to buy @Acmemfg 's 36-ounce beast
