Review on Extremus 421 Hydration Vacuum Insulated Water Bottle: Ultimate Stainless Steel Double Wall Thermos, 17 Oz, Leakproof Top, Carry Strap & Bottle Boot by Noe Miceli

I've had this bottle for a week now and it does what it says on the tin. I put the bottle in the fridge overnight and take it out in the morning to go to work around 7am. When I come home after 5pm the water is still cool. I had no leaks and put the bottle on its side with no problem. The rubber boot is a nice feature as it can stick to the surface you place the bottle on. Without them, the metal would slide easily across the surface you place it on. The description says it's 17 ounces, but it's actually a little less, but not by much. I fill it with a 16.9 ounce bottle of water and when I put the cap on it squeezes out quite a bit of water. So it's probably 16.8 or 16.7, so it doesn't matter. This is a good bottle, feels comfortable in the hand and the carrying strap is a nice feature, when your hands are busy you can easily carry it with one finger. The hole is not too small, I was able to put a bottle brush in there to clean it. It's a good size for drinking. I think it was a good buy.
