“amazing!! brought the product for my boyfriend as he works long shifts. i tried the bottle when i first received it and it kept the hot water hot for 2 days !! defo worth the money”
“does exactly what it is advertised to do, I took it on holiday in temperatures of 36 my cold water stayed cold, that was at least 8 hours, and hot soup, coffee stays hot, I have only kept it for 4 hours but it was as hot as when I made it.”
