Doesn’t maintain hot too long.
I love this cup because the material is good for heavy duty jobs like mine. I took off one star because it does keep hot but not for super long, it lasts hot for about 2-3 hours. Other than that it’s easy to wash and the magnet that comes on the cup is super strong which comes in handy for not loosing it. It magnetized on to the cup.

It's the best.
I'm picky on my coffee cups. Klien though has made a great cup for ones like me who work construction. This tumbler not only keeps your coffee hot, but is tough as hell. I can't count how many times it's fallen, dropped, or accidently kicked and still works like new. The rubber bottom and sides grip great. The magnet is strong and helps with tipping over, or possibly dropping. The locking lid also helps with spills.
