This is hands down the best water bottle I have ever owned. This is the 3rd Contigo water bottle I have purchase but the first metal on.  I had not noticed how much better the water tastes from a stainless steel container vs a plastic one.  The Double-wall vacuum-insulated aspect of it keep my water nice and cold for many hours.  I have noticed that I crave the taste of my water from this bottle vs my other Contigo bottles and I end up drinking far more. I am about to order a second one for my desk at work.
