Double Shutoff QC's?

[Tony Shelton]

Does anybody use double shutoff qc's like the carpet cleaners use? Or are they too restrictive? These are also called Hydraulic qc's.

I do not use them

We have them on our little indoor machine and I think they suck. The little shut off pins inside get stuck a lot. They are much harder to press together sometimes. Just another reason I hate going inside!
