Product review (5 stars): I'm happy with these filters
This product has worked as advertised.  The installation went smoothly; don't forget to follow the directions and run at least 2.5 gallons of water through the filter before drinking.  The water flow is good and tastes fine.

I can't say if it will last 6-months but the savings compared to the OEM filter.  However, the purchase appears to be worth it at 80% lower unit cost compared to the OEM filter.  If each filter only lasts 3 months, I'm still ahead.
