Not as sexy as condos or Cornwalls, but yesterday I finally had had enough of these softjaws. 2 tiny weak magnets that would cause the jaws to fall off the vise with not much more than a strong breeze, and thin silicone pads with a horrible retention system that never worked.
Now, 3 double stacks of rare earth magnets that are glued in with JB weld, and then some thick leather pads that I made out of scraps that I had laying around, glued in with contact cement.
I'm not sure if this is gonna work out or not, but these were getting binned out of frustration anyway.
Time will tell.
