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

I received this item for free in exchange for my honest review. I've had my water bottle for a few weeks now. It keeps water cold and keeps coffee hot just fine. At room temperature, the ice water stayed very cold for at least 8-10 hours and the coffee hot for about 4-5 hours. I've washed it in the dishwasher a few times and it's ok. I don't use a shoulder strap, so I can't comment on that. I like that the bottle isn't very thick; it fits well in the cup holders in the car and in the bottle compartment in the backpack. The only thing I don't like about the bottle is the narrow neck because it's difficult to put ice in it. I have to find slim cubes in the freezer so they don't get stuck in my throat. The inside diameter is about 1 1/8 inches at the narrowest point; If it were about half an inch wider this bottle would be a 10/10 for me.
