I purchased a Stanley The Quick Flip 1.06-liter and expected it to keep boiling water hot for a long time, but I am very disappointed with its performance. When I filled it with boiling water, it cooled down within 5–6 hours, which is far below the level of insulation I was expecting from this product.
On October 25, 2025, I experienced this problem and then contacted the relevant company and sent the product in for inspection. However, I was informed that there was “no fault” with the product and that it would be sent back to me, and on top of that, I would also have to pay the return shipping fee.
I do not find it fair that I am expected to cover shipping costs when the product clearly does not meet my expectations for keeping beverages hot. I request that my issue be reconsidered and that the product either be replaced with one that performs properly or that a refund be provided without any shipping cost being charged to me. I kindly ask that my complaint be carefully reviewed and that a solution be offered that does not cause me additional financial loss and restores my trust in the brand.

I purchased the Stanley Quick Flip model just a week ago, and it has quickly become one of my most regrettable purchases. The plastic part of the lid was jammed, and as soon as I finally got it open, the lid flew off with a surprising force. Hot liquid splashed onto my body, resulting in burns that ...
I purchased a Stanley thermos with a lifetime warranty, expecting high quality and durability. However, despite registering it in the system, it fails to keep liquids hot, cooling down within just one hour. A thermos that can’t retain heat is completely useless. I paid a significant amount for this...
