Review on Stay Hydrated Anywhere with H2 Hydrology Water Bottle - Double Wall Vacuum Insulated Stainless Steel, Wide Mouth and 3 Lids in 5 Different Sizes - Hot & Cold Thermos for Sports Enthusiasts by Sean Julian

I've had them for about 6 months now. I bought two 64oz bottles. They are amazing. I can fill it with ice and it will still have ice in it the next day. It really keeps you cold. My daughter recently broke the lid so I bought a different brand due to the color. It looked the same. I was terribly mistaken. I added ice water to this other brand and after a few hours it melted. It doesn't hold the cold like hydrology. So not all water bottles are the same, even if they are both made of steel and look the same. I can highly recommend hydrology. I'll end up buying one more of these.
