Warranty

What a fault looks like

• Lost vacuum. The clearest symptom is sweating. A working dual wall body stays dry on the outside; if condensation appears on a cold drink, the vacuum gap has been compromised and the insulation is gone with it.
• Cap that will not seat. The swap system should hold a can firmly with a short turn. A cap that spins without gripping or refuses to seat is a defect.
• Coating failure without impact. Powder coat lifting or flaking on a body that has not been dropped or scraped is a finish problem.
• A flask that leaks with the cap closed. The seal is the whole point of that product.
• A bumper that splits at a seam rather than tearing where it was cut or caught.

What is not covered

Scratches, dents and chips from ordinary use. A body that has been through a freezer or left in a car in August, both of which stress the seal. Discoloration from cleaning products that are harsher than the care instructions allow. Loss and theft. Damage from putting the flask in the bottom rack of a dishwasher, where the heating element sits, rather than the top.

Raising one

Have the model, the color and the approximate purchase date ready, plus a photograph that shows the fault. If you are still inside the retailer return window, use it first: a replacement in two days beats any warranty process. Outside that window, send the photograph and those details to [email protected]; the postal address is on the contact page.
