What to know before buying

Listing details to confirm

Listing details are inconsistent: the title and feature copy state 650ml total capacity and two 11oz bottles, while the details list 22 Fluid Ounces and the page also says 650ml. The listing gives a 1.4Kg empty weight and 1.65kg filled in feature copy but does not provide a separate verified measurement. Its 24-hour cooling, TSA approval and pump/nipple compatibility are manufacturer claims, not independently confirmed. Confirm the capacity and dimensions suit your needs.

Customer feedback highlights effective cooling, convenience, quality and portability, with one customer reporting use through a full eight-hour day. Views on size differ, and durability feedback is mixed. That makes the cooler's substantial stated height worth considering for commuting or travel, while the reports of cold retention are encouraging but do not establish the listing's 24-hour claim.

Positive themes

Customers report effective temperature retention and convenient, portable use.

Mixed feedback

Customers disagree about whether the cooler's size is suitable.
Durability feedback is mixed.
