OSO Polymer Collars is rated 3.0 out of 5 by 1.
Rated 3 out of 5 by from Not a good as the standard OSO or spring clips Purchased these a few monsters ago, I had a pair of the original OSO aluminum clips that I used at my local box. The box provided spring slips but I wanted to stop adjusting weights in the middle of a WOD. To save a few dollars on my garage setup, I decide to purchase these instead of the OSO aluminum clips. I wish I had spent the extra money and got the aluminum set. These slide as much as or even more than the typical spring clips. They look nice and mechanically function, but the small cam used to hold it in place does not provide the grips required.
