I bought mine used and reached out to the owner, mine was made by Rogue back in the day, it was a bucket list equipment for me. I made little ring spacers out of scrap wood to put in-between the plates to help load and unload.
I got mine super cheap on marketplace, this is worth buying full price if you need it. I think its specific angles help target muscles, extremely well made and I would buy more from them.
I bought mine used, the new ones are expensive, but if you specifically need those they are worth it. I am not really dropping mine, but I like the most on these is the sizing makes them oversized almost like a circus dumbell to make the lift harder.
