I have the older style with the flat roller and the threaded pin rather than the quick pop pin. The pop pin is probably a huge improvement, the threaded pins take make it a hassle to move the jhooks. I have no issue with the flat roller and I'm sure the grooved roller is perfectly fine too.

Works as intended to make a 6 post rack. I chose the 24" depth so that even with weights stored on one upright and a bench loaded on the next, you can still fit through to spot.

I have the wide flat pad and installed it on the Griffin flat bench. It's compatible and works great. Rep's reputation for the bench pads is well earned.

Overall a decent bag for the price. the top rolls down so you can easily adjust the size of the bag though the buckle system doesn't always cinch down as tight as i would like so I usually supplement with duct tape or a separate nylon strap and buckle I had. I usually keep it loaded to 150lb and I wouldn't go that much smaller since you'd have to roll down even more fabric from the top. I've had it loaded as heavy as 250 and it handled it well. There's no inner liner so it does get dusty when dropped repeatedly.

Very solid bench. The knurled handle is mostly for looks, but it does look pretty cool. I've since replaced the pad with a Rep wide pad, which is compatible with zero modification.

Very solid built belt. Used to be the best of the best but other brands have stepped up lately. I use mine for belt squats, weighted dips/pullups, and reverse hyper leg strap. The more cushiony belts might not be as usable for the reverse hyper leg straps

Fun grip implement similar to the Rolling Thunder. Some people strip the paint and allow the bare metal to patina for a more grippy surface. I kept mine painted and have the larger diameter ~2.5" so if I ever use the real Rolling Thunder it will feel easier in comparison.

Very strong magnets. It seems overpriced for such a small amount of actual weight, but for me it saved hundreds of dollars of dumbbells. I have cast iron hex head dumbbells in 5lb increments up to 30lbs and then 30 to 100lbs in 10lb increments. These magnets allow me to hit the 5lb increments 35, 45... to 105 which saves me an incredible amount of space and money for dumbbells that I would only use infrequently anyways. I decided to keep the 5lb dumbbell increments under 30lb because the magnets don't stick that well to the smaller dumbbells. The magnets stick really well overall but if the surface is rounded or uneven they might not stick as well during quicker movements. For most of my dumbbells it's fine, but there are some i have to be careful about where and how I stick the magnet.
