Query: Not so good...

I'm sure the filter itself is decent enough, but I never even got that far. The product comes with plastic quick-disconned fittings that get fastened to the copper tubing by compression. Problem is the compression nut is brass, and the fitting is plastic. If you dont' have the threads exactly lined up, it is extremely easy to strip the threads. Which I did... Haven't looked yet how available a replacement quick-disconnect fitting is, but my guess is not readily available. Recommend to GE that they make the quick disconnects out of brass or something more robust than plastic.
