X-3 Series QuickSlide Spotter Arms

I like these spotter arms more from a functional standpoint than the Rep PR-4000 ones. Although I don't move them all that often, I like these better than the ones where I have to twist and pull out because of the Athena cable attachment I have. The build quality isn't quite as good as the Rep ones because these only have UHMW tape on the inside, but functionality wise, they're worth it in my opinion. Even though they take up the same number of holes on the rack, the actual spotter part of the arm sits about two inches lower than Rep spotter arms because of where the arm is centered. I like that feature. With the scratch and dent discount, the price was great for this functionality.

I wanted to really like these, but they are just ok in my opinion. The concept behind them is awesome, the quickslide looks like it would make it easy to quickly adjust positioning on the outside of my rack (doesn't fit inside of my 24" rack). That said, in practice I find I don't move them enough in a single workout to really justify the quickslide mechanism (thats a me thing), but I also dont find the mechanism to move and lock quite as easily as I would have expected based on the design. It takes enough fiddling that if I had to do it over, I would just buy normal safety spotters that flip down or use a hitch pin. I was also semi-rough on them my first session and accidentally took off some paint the very first day when I caught my barbell knurling on the edge. It is coated with PVC/UHMW, but i was able to catch it at an angle where I really took out a chunk of the paint from the edge next to the pvc, so I'm not sure about the design/build quality. I'll keep them as they work just fine, but there are probably better options and I think I'd use the quickslide feature much more for j-cups than for the spotter arms.
