Product review (2 stars): Was good.  Design changed and now does not work well.
We had been using this filter system for a couple years.  Several months ago, they changed the design of the replacement filters.  First, when we received our order, one was broken open and tiny pebbles were everywhere.  So, the newer setup is not made very well.  Also, the filters went from working a couple months to only about a week at most - and  the new ones do not work nearly as well as the old ones.

It's too bad.  This was a good product, but I guess like so many other companies they are now trying to cut corners to increase their profits.
