Don't forget, if you want to adapt the paint pad, you have to undo the small screw in the handle and turn the handle 90 degrees. The new pads are slightly different, you have to cut off a small piece of the plastic inside to get it to fit once you have turned the handle, it's easy to see what you have to do once you pull the two pieces apart.
These swivels work really well, and I have been using the same one for over a year now.
