Product review (5 stars): Filters do not work - No water flow
Update:
After I posted this I found that the reason no water was coming from the water dispenser was because the water utility company was doing work in my neighborhood and had temporarily turned the water off.  There was no water pressure in my house.  Once the water was turned back on the filter worked just fine.

The other two issue still remain:
1. The lubricant tubes are almost empty.  I had to put a lot of effort into squeezing the tubes to get a tiny dab of lubricant out.
2. The filter does not have an alignment indicator like the Samsung model has, which made it difficult to properly align and install.

Bottom Line:
I would buy again, but I hope the manufacturer addresses the two issues above.
