The read
What's actually worth knowing.
The flip straw design lets you drink without removing the lid, and the lid snaps shut to prevent spills, but you need to make sure everything is assembled and tightened properly for it to actually be leakproof.
This tumbler is only for cold beverages. Hot liquids, carbonated drinks, citrus, and milk products can damage it or cause the lid to fail, so it's not a multipurpose bottle.
It's dishwasher safe, but Stanley recommends hand washing if you want to preserve the color and finish, since the dishwasher can age the appearance faster.
As of Aug 15, the STANLEY Quencher ProTour Flip Straw Tumbler with is a good price at $45 — versus a $44.74 typical price and a $33.75 12-month low, based on Amazon's own price history.
