Good cup
Great cup, love the long lasting seal.
the magnet fob is strong enough to hold a full cup which is great.
Holding warmth...id say 6/10
Keeps warm of its full for about 3 hrs give or take but half full it tanks pretty fast.

Sturdy good grip
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..
