Review on OISHHI Triple-Wall Stainless Steel Water Bottle - Vacuum Insulated Bottles - 34oz, 20oz Hydro Sports Flask with Leak-Proof Cap - Silicone Bottom Thermos Mug by Kenneth Harris

This bottle is very well made. At first glance, the color is exactly the same as in the product description. The brand and logo are revealed by cutting out the outer layer of lacquer and the underlying stainless steel. It's very well designed. As for the actual functioning of the bottle, I did two tests.1. Hot drink test: At 9 p.m. I filled the bottle 1/3 full with hot water from the kettle, closed the lid and went to bed. At 7 a.m. the next morning, the water in the bottle is not boiling hot, but it is still warm enough to be considered a hot drink. Cold drink test: I filled a bottle with room temperature water and ice at 8am at work. When I left work at 5 p.m., there was still a small amount of ice in it. The next day at 9am the ice had already melted but the drink itself was still cold. From my experiments I can say that this bottle actually works as advertised. This purchase is money well spent!
