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 Manni Diaz

I looked at different brands and sizes of bottles and based on the reviews and price I decided to give it a try. Since I have not used any other devices of this type, I can only comment on this. It is great! Sometimes I wasted so much water because she warmed up by the bed at night or kept putting the warm bottles in the fridge to cool them down. The water stays cool for over 24 hours in my 220oz. I left him in the Florida sun for a few hours to check in, in my car for a few hours in the Disney parking lot, etc. and he always had cool water to drink. When I wake up at night, I drink cool water without getting up. I start with ice and fill with water. As promised, the bottle fits perfectly in my 2001 Honda cup holder. I first bought the 64 oz to kayak and was so impressed that I immediately bought this for travel afterwards. A great addition I found here at Revain was a protective silicone bottom cover which made it even more comfortable to use! I say I love it! Buy it!
