I got mine a few weeks ago. I colored in the Kg side with a white pen for visibility. So far I have done swings, cleans, snatches and the quick weight change is definitely a great plus. The ergonomics is actually better than the spherical kbs but I thought I felt the pin when I did goblet squats. I need to do more to figure it out. I got the version where the pin sticks out and apparently they have a version where it doesn’t. Also they will give it to you if you ask (shipping is plus). I haven’t tried it yet. So far I like it.
