These are ~fine but it's dumb that the mounting pin is inline with spotter arm, because it means the whole thing can rotate in place and there are no holes for pinning it in place with a mag pin or hitch pin. Doesn't really happen in practice, but over time as you slam things into the rack they do start to twist out of place. Missing UHMW in a lot of places that the bar can contact, and the UHMW is kinda ugly, cheap textured UHMW which doesn't affect performance but just doesn't look as nice as what Rogue uses for example. In this price range I think the Bells of Steel ones look like the most functional design, but the hitch pin hole on those probably won't line up properly on a metric rack like REP. Not as important with that design though because the welded pin is in a smarter spot and the spotter arm can't rotate around the pin.
