Rogue Monster J-Cups is rated 4.7 out of 5 by 3.
Rated 5 out of 5 by from High Quality I just got these today. Man do the pictures not do them justice. I don't know what it is about pictures, but they really don't capture just how solid and big these things are. They are beautiful. I bought them because I plan on getting a Monster power rack and my current el cheapo rack came with really pathetic j-cups that seemed wobbly even with only 315 on it. My rack also is 3x3 with 1" holes so these were the only choice to make. I put the Rogue babies on and slapped 405 on it just to see how it stood up. I have to say it seemed like nothing to them. It seemed very obvious that they can handle 500 or 600 lbs. Not sure I can say the same for the rack itself. I haven't worked out yet today so all I did was take it off the rack and put it back to see how they may have wobbled, etc. No wobble at all. Plastic on the bottom and in back, and there is a slight angle on the cups so the bar rolls to the back gently so it doesn't ever hit the very front of the cup that has no plastic. I know Rogue puts some specs on their products for what works for which product, but it would be nice if the specs were spelled out better. Not every newcomer to the site is going to really know what Echo, Infinity, Monster Lite, and Monster really mean. A chart with the rack thickness dimensions and hole size for each type of rack and product would really clear up the confusion real quick. I almost bought the Monster-Lite because I was going to buy the Monster-Lite power rack. But because my current rack has 1" hardware I needed to buy the Monster j-cups... and this has resulted in locking me into a Monster power rack when I pull the trigger on that. I'm not complaining... it's probably the better rack for me anyway.

Rated 4 out of 5 by from Standard Moster J Cups Great for the price. After a year of usage, the bar has rubbed the paint off. Sunce there is no protective plastic in the front in has started to rub the bar. Will probably upgrade j-cups in the future.

Rated 5 out of 5 by from Rugged Design These J hooks are the real deal. They are built to handle the rough handling of powerlifters. I am using them to replace the cheap J hooks that came with my Fitness Gear half rack that I use in my home gym. I love the nylon inserts as well. They let you move the fully loaded bar around to get it in the right position for the lift.
