We love the compact, cageless form factor, the speed and ease of adjustment, and the overall fit and finish of our S560s. We’ve never had the plates jam when placing them back in the cradle, and never had a loose plate after adjusting. The mechanism provides plenty of haptic feedback to let you know when the handles have locked into the selected weight. The knurling is tame, as other reviewers have noted, but as long as our palms aren’t sweaty, there’s plenty of grip. I may add a silicone tape wrap for added grip in the future.
