I bought the Vital bottle nearly 2 months ago and I love it. I had a different filter bottle for years before, but the filters just became too difficult to open. Searched and found this one. 
It doesn't leak, closes the drinking piece when you close the lid, and it's easy to clean. And of course it takes the horrible taste out of tap water, which is the reason I bought it.
As per the instructions I soak the filter in boiling water regularly to clean it. 
Definitely recommend it if you're thinking of buying one.
