Stanley Thermos Not Keeping Water Hot for More Than One Hour
On May 8, 2026, I purchased a “Stanley Classic Vacuum Insulated Stainless Steel Thermos 1.9 L Green” from the Black stors seller on N11. I have been using the product for approximately three months, and since the very first day, the hot water I put inside becomes lukewarm in less than an hour. The thermos clearly fails to provide the heat-retention performance it is supposed to have. Since the product does not fulfill its basic function in its current condition, I believe it is clearly defective and faulty.
Although I requested that the product be evaluated under its warranty and replaced with a defect-free equivalent, I was given the same response twice within ten days—asking me to “provide a detailed explanation of your request”—without being offered any concrete solution. I purchased this product trusting both the N11 platform and the seller, but it has caused both disappointment and inconvenience.
My order number is 203684637334. I request that the product be treated as defective under the applicable warranty and consumer protection regulations and replaced with a defect-free equivalent without subjecting me to further unnecessary effort or loss of time. Alternatively, if deemed appropriate, I request a full refund.
