    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..
