Product review (5 stars): Even better than new at a fraction of the cost
Works just like the more expensive options, same clean clear water at a fraction of the cost.

There is absolutely no reason to get any thing else. Tested with my water tester and although not as clean as the RO filter at the sink it is far better than the tap water and every bit as good as the filter that cost nearly 5 times as much when I last replaced. I am going to put this on a subscription plan so I need not worry about having a fresh replacement when I need it.
