A year ago I moved to a new apartment that didn't have any filtered water readily available. Nothing on the 'fridge door or any of the sinks. Before getting anything more fancy, I just got one of these water bottles, and it worked wonderfully.
Filters are cheap and easy to replace, and make a very noticeable difference. The straw was definitely not something I was seeking out, but it's now one of my favorite aspects of this bottle. Because the lid opens using a spring-loaded button and the straw allows you to drink without tilting the bottle, it's easy to use one-handed.
It does exactly what I need it to and a little bit more!
