Takes me back to building with LEGO as a kid, finding new ways to use my pieces in ever more practical ways. That puzzle is endlessly rewarding to me but is bested by the end result: More crap but less of it on my floor.
I already own original OSO collars. I didn't need to buy these but I am happy I did. I am a sucker for purple and this shade is lovely. That's enough. But these collars are also far more compact and clamp more securely than any other I have used previously. Perfectly pleased.
Since eclipsed in utility by the proliferation of open trap bars, if I was starting over, I would not buy it again. But it's still robust and useful as hell. I use it weekly for deadlifts and power shrugs.
For benching, it reigns supreme in my home. Takes a minute to initially find your balance point (and figure out the plate math) but for your efforts, you're rewarded with a great increase in comfort.
