What owners single out
Buyers' weakest aspect—leak resistance—aligns with video reviewers' concern that the lid is not fully leak-proof and can spill if turned upside down.
In their words
“Received my order quickly and looks exactly as show in their site. Cup is an easy grasp handle and lid has a great seal with no leakage. Even with the straw it was knocked over and was surprised nothing spilled out. Beverage was kept cold well over 10 hours and I could still hear bits of ice when shakin.”
Christine · verified purchase · stanley1913.com
“Bought as a very large "mug" as an alternative to the standard thermos. The mug is they way I expect it to be. Very robust as well as performant. Keeps hot, very hot for very long and ofers the handle to keep the process of drinking easy.”
