I bought this mainly for drinking water as I hate the taste of tap water here. I also despise small necked bottles which are harder to keep clean. I love that this is so easy to clean and change the filter and that it's transparent which aids in seeing if it's clean at a glance. Great lid and popup sipper that closes when you shut the lid. Easy to unscrew the lid and put it back without much effort which is great as I don't have strong hands, no leaks at all. Filtered tap water now tastes far better and I can now drink the amount I am supposed to daily!!! Current cost of the filters not so great on the date of this review, but that might improve so I am sticking with it. Love the pink and blue versions.
