What to know before you buy
The Quencher is built to sit in a cup holder. These are the limits to know about.
It is not leakproof
Stanley says the H2.0 FlowState is not fully leakproof. Its leakproof model is the ProTour, with a flip straw that locks.
Tall and heavy at 40 oz
The 40 oz is about 12.5 in tall and weighs 1.43 lb before you fill it.
No hot-drink number
Stanley lists 11 hours cold and 2 days with ice. It gives no time for hot drinks on this tumbler.
The lead seal in the news
In early 2024 Stanley told NBC News that a lead-containing pellet seals the vacuum insulation under a steel cover on the base. Stanley said drinks do not touch it, that it is exposed only if that cover comes off, and that it was working on other sealing materials.

Core colors list at $45 and $50. Some seasonal editions list higher, such as $55 for a 40 oz.
