One of the most important things for me in a water bottle is whether it's going to get my stuff all wet or not. When I fill my bottle I'm usually leaving the house with a dozen things in my hand and the probability that I'm going to spill my beverage is relatively high. This doesn't leak if turned fully upside down. 

I've used this brand for a number of years for our travel coffee cups. They seem to really be into innovation. The 'autospout' button and locking mechanism is pretty slick. One push of the button releases the mouthpiece from the cap. Sometimes it flicks a bit of your drink on you which can be avoided once you know it's going to happen. It keeps the mouthpiece covered until you're ready to drink from it, which is great and hygienic. 

I appreciate that the bottle is marked dishwasher safe as well. Things that can't go into the dishwasher to be cleaned don't last long in my house.
