Product review (3 stars): Had to turn water pressure down to make it work
Filters water fine, but had one issue:  When I installed it, it started making a really loud knocking noise.  I turned the water pressure down and it works OK, it just doesn't have good volume, and I had to turn the hot pressure down as well to balance out the pressure on the sink it's attached to.  Now I have a low-pressure sink, but a functioning water filter.  I've had this arrangement working for 6 months, but I won't be buying this product again.
