Had my dad make some of these before I upgraded. Not much better than just rolling the weights onto a plate.

Was putting off investing in one of these until I spotted it second hand. Does a great job and makes loading/unloading standard deadlifts much easier.

One of many bought second hand. Love using these with the smaller pins instead of ones that the pins are almost as tight as a barbell.

Got a couple of these that I've used off and on as I've adjusted the number of dumbbells in the gym. Thankfully these disassemble somewhat easily for storage/moving.

Cheap older weight more than anything. Currently use a bunch of these for when I visit family back home. Also have a lot collected for future projects.

My biggest critique on this bar is the assembly. I had to fight for a while to get it bolted together and even with the holes appearing to be lined up perfectly, the bolts took a while to get started.

They are bumper plates but nothing special. Used them a lot in a deployment gym with a crossfit setup. I'm never a fan of plates this thick where you won't fit many on the bar.

Very heavy duty system, but the one I used may have had user errors during assembly. There were spots where spacers were needed on the weight horns or otherwise the machine would rub the plates causing damage to bumper plates. Way overbuilt and prices for any home or small gym.
