I have them on mine. I absolutely love them. They do extend the implement slightly, so the range of the original top link becomes limited when using them so I bought another slightly longer top link, which is really a good change to make anyway since it adjusts so much more easily than the original top link. Changing implements is a breeze for me. I simply back up to the implement, and push a little until both Pats hooks are even with it, lift the 3PH until it clicks on both sides (kind of guides itself in), then hop off and hook up the top link which is easily adjustable and the PTO if a PTO implement. Very easy one person changing rarely takes me more than a couple minutes to change between anything. I have adjusted all implements to the same width to match the one that is not adjustable so all 3 are very easy to deal with.
I had previously had to help friends hook up on their tractors without Pat's and would never go back to fiddling with it like they do. I recommend Pat's or a quick hitch system to anyone and everyone.
