Product review (5 stars): Works fine
Kit as advertised.  The top tray in my system had lost it's rough bumps overtime and wasn't distributing the water as well over the filter.  They say you can put some dishsoap on it but thought after 15 winters new plastic casing would be in order.  It  wasn't hard to change most of it.  I couldn't get the water inlet connection off (must have corroded) so I didn't end up changing that small filter but saved the part incase it becomes an issue later.
