Product review (4 stars): Perfect replacement fit
Fit perfectly in my LG refrigerator.  I like the fact it came with silicon grease for the seals.  Apply sparingly.  Ran 4 quarts through it to prime the filter and had very little residue or color.  Water tastes great and pressure is good.  1/2 the price of the local box stores.

My only complaint is that it seems to add quite a bit of turbulence to the water flow.  Where we used to have a quiet single stream, it's now quite noisy and seems to splash more.  Could be the increased pressure.
