What to know about the Stanley Quencher 40 oz

The Stanley Quencher H2.0 FlowState 40 oz (1.18 L) is the handled tumbler that made the brand a phenomenon. This link goes to the Peony colour, a pink shade. According to Stanley, it's made of 90% recycled 18/8 stainless steel, BPA-free, with double-wall vacuum insulation.

The FlowState lid rotates between three positions: a straw opening (with a seal that holds the straw in place), a drink opening and a full cover. The handle has a comfort grip and the narrow base fits most car cup holders. On its 40 oz listing, Stanley claims about 9 hours cold and up to 40 hours iced.

Important: the lid resists splashes, but it isn't leakproof. If it tips over, it leaks. For a backpack, Stanley sells other models (the ProTour line) with a leakproof lid. Stanley says the Quencher is dishwasher safe, and it's covered by the Built for Life lifetime warranty.

FAQ

Is the Stanley cup dishwasher safe?

Yes. Stanley says the Quencher H2.0 FlowState tumbler is dishwasher safe. The lid and straw can go in too, though hand-washing helps them last longer.

How many litres is a Stanley 40 oz?

Do Stanley cups contain lead?

Stanley says a pellet used to seal the vacuum insulation at the base contains lead, but it's covered by a stainless steel layer and never touches the drink or the user.
