Worked great to add the additional stage. The rings snapped right on to hold the filter and hooked right up.

Works great!

We can taste a difference in the water and raised PH by about 1.5 consistently. Used my fish tank PH tester kit :)

Works fine and easy to install. I exceptionally like the part that everything is just click on and no screwing or tightening involved. This is made exceptionally for the spring unit which i have already installed. I would have like the tube to be longer as it was too short in my opinion. Anyway it worked out well.

Works good. Clips two filter modules together, and has the plumbing part to make the process easy. Perfect thing to use if you buy iSpring mineralizing modules.

I used this to add on the additional 6th stage that I later desided to install on my Ispring RCC7, which was the alkaline/mineral filter. Worked like a charm! The larger part connects onto the RO membrane housing, and the smaller part connects onto the alkaline filter, so that you have a v shape at the top coming off of the RO membrane consisting of the 5th stage carbon filter on one side of the "v" and the towards the inside of the cabinet, you have the other top of the v shape, which is the alkaline filter
