Bought this because it had good reviews and looked sturdy... with the previous, other name tumblers, if you dropped the lids they broke and the company dont have replacement lids so you had to buy the whole thing! Gets expensive... no issues with this tumbler.. my husband really likes it, fits our cup holders and has a good grip..

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.
