I really value the NSF certification, so I think this is a great product. I enjoy the peace of mind I get from knowing my water is very well filtered. I wish that the filters lasted longer, and I dislike the bad taste the water gets when it is time to change the filter, and of course I wish the filters weren't so expensive. But I do think it is worth the cost overall. I like the design of the pitcher. The first time I tried to put in a filter it was very challenging, but then I got the hang of it and it is easy now.
