I love my Stanley Quencher H2O Flowstate!!! The only issue I'm having is that the lid like vacuum seals, making the tumbler EXTREMELY difficult to open. I have Multiple Sclerosis, I purchased 3 tumblers for me and my little family. They are not disabled and both agree that mine is extraordinarily difficult to open. But, I'm rarely alone, so someone will get it for me, lol. Truly an investment, as they are a bit on the pricey side. But they are worth the money. I do wish that the straw was metal. The plastickie vinyl ish straw stains with my lipstick and is not good for the environment. I will be purchasing other Stanleys soon.
Purchased for my Christmas Stash boxes I fill all year long for family. I did purchase non-OEM lid, pro-tour, from online so they could put it in their bag and go. I wish Stanley would offer just the Lid-Pro-tour version-for purchase with each Quencher with the matching colors as I LOVE the Pro-Tour more than the Quencher alone. Works with our Busy life- and Stanley- You're not just for the Working "Man/Woman" anymore- You're for everyone- Working-Adventurer-School-and the creative decorators... So we need both lids to buy. Even a standard ALL CLEAR Pro-Tour would be nice to start- I can dye it to match.
I am obsessed with these mugs I must admit I probably have too many at least my husband would say that. The reason for the 4 stars is it hasn't been keeping it cold past 6 hour.
