This product doesn't hold cold as advertised. I placed mostly ice and small amount of water as my preferences. It melted all the ice within few hours. The unknown water bottle that I brought from Ross holds better cold and kept the ice longer than this one with the fraction of the price. I like the one hand use opener though.
Revomax Vacuum Insulated Stainless Flask, 950ml / 32oz
Haven't received the bottle in 2 weeks yet from Germany to France thanks to DHL.
I have been using it for a while, the product is good, the temperature is good. I can advise you to buy.
