Product review (1 stars): Not Watts Premier
Part arrived and was not Watts brand, but a generic brand, "Etech"

That same Etech one was available at my local hardware store for $4.99!

Amazon needs to update this listing or charge the lesser price.

BTW, this one is 3/8 quick connect so you will need a 3/8 to 1/4 adapter if you decide to use it. They do make one with a 1/4 quick connect for 99% of the r/o systems out there.
