Had them on my 2014 Pro-lite for three years. 250-275lb pretty aggressive rider. Never got a bow in them or loosened up any rivits surprisingly. They shed snow very well and don't ice up, but they don't have quite the traction of boards with screws. I actually had to add screws at the bend at the rear of the boards after slipping a foot and falling off a handful of times.
I helped a friend install a set on his 2016 and the fit left a lot to be desired. Definitely a two man operation with about 4 clamps. To make it look decent when finished. Between that and the experience I had with the cat pro MTN boards I have now, I'll be spending the extra money on BM Fab or Skinz for the next sled.
