I have been loving all of my PRX gear. I have the rack and a set of bumper plates. All my bumpers have been the crumb plates but I snagged an extra pair of 10's when then diamond crumb was in stock. They look nice but I was disappointed to see some chunks missing near the center where the ring sits. I expect that from a walmart knock off that I'm paying half price for but when I'm paying this much I expect a little better as far as quality control. Other than that they do function as needed so far but I did want to note that for some improvement!
Awesome plates and great customer service!
