Review: Hot and Cold tests passed perfectly - I bought this as a milk bottle to go alongside the Milton thermal flask. Tested with hot and cold water and remained suitably cold and hot for either milk or tea for as long as I needed it. I tested for 16hrs and barely any temperature change so I would guess that it will still be great after 24hrs. It does help to have it filled as much as possible and the lid became slightly warm but never hot. Great style and large as a litre bottle. The litre bottle has the lines around it near the base as seen in the photos. Great value and great product.
Review: Very good and realiable product - Very good and realiable product
