Lid design fails to prevent liquid escape.

Grateful experience

Tumblers

Purchased at the local store.

Works well -- for a reasonable price. The instructions say to handwash it, but I see at least one reviewer who washes their tumbler in the dishwasher.

Some people mentioned liquids building up in the lid. No problem. Place warm water and a drop of dishwashing liquid in the tumbler, secure the lid, shake, and voila! everything is clean. Rinse well with warm water, shaking with the lid on it again, as many times as necessary to get rid of suds.

I Plan to Buy More of These

I measured this cup to hold at least 480 mL and it does an excellent job at insulating.
I don't know how durable the lid mechanism will be.
It stacks to some extent ( about half way )

excellent insulation, good capacity

They put sticky price tag aver the vacuum cover and thus one pulls off the cover with the price tag removal. They should think before placing the price tag.

Price tag placement

The plastic cap is not airtight and leaks very easily. I expected it to seal properly, but liquid seeps out even with minimal movement. Definitely disappointing and not reliable for travel or storage.

Mainstays Stainless Steel Double Wall 16oz Tumbler with brushed stainless steel finish and clear spill-resistant lid, vacuum insulated to keep drinks hot for 6 hours and cold for 24 hours, sweat-free design, fits most car cup holders, suitable for on-the-go beverage storage.
