I got a lot of different items in my order, and I was very happy with all of them except the barbell collars. One if them is rock solid, but the other is loose and falls off during lifts. I can’t tell why it’s defective, it looks the same as the other. However, it’s unusable and a little bit unsafe, which was very disappointing for $50 collars. Other than that one defect, I really like the T-3 power rack, vertical barbell holder, loading pin, and silencer pads. I would like to get the collar replaced if possible, but everything else has been really good. The power rack is so solid that I don’t need to bolt it into the ground. Shipping was also impressively fast (2 days from my order!).
