Product review (4 stars): so far, so good
Found these and read some good ratings on them from previous buyers.  They were shipped very quickly and waiting for me at the house when I returned from a trip.

They installed easily as expected, and seem to be providing good quality water filtration, with pretty much all notable issues taken care of.

The filter has only been installed for about a month so long term results are not available yet, but for the price, I think it is a good deal.
