This piece of equipment is excellent value for the money. It is well built and light enough to easily attach to my Rep Blackwing bench or remove for storage. The extension movement feels good. I would prefer a bit more weight at the bottom, stretched position but that might be improved by adding a cheap resistance band. I don't like the feel of the leg curl movement but that may be due to my own biomechanics and not the equipment itself.

This is a nice leg developer option for sure. Works fine on my REP Nighthawk bench. Just needed an extra pop pin hole to line up better. One thing I wish they would add is band pegs. Price and functionality can’t be beat.

It's pretty good for leg extensions as far as plate loaded attachments go. My problem with it for leg extensions is that the weight post is too skinny and my plates flop around, causing weird behavior particularly at the top of the lift. I 3d printed myself a sleeve that closes the gap, and with my plates fitting tighter, it feels okay and toasts my quads. For extensions, I can hit the stopper at full extension. The ROM isn't wonderful, but at least it's at the end of the contraction.
For leg curls, the ROM feels very limited, and unless you stop yourself at what feels like a half contraction, you slam the bar into the stopper. This happened on my very first rep, gouging the stopper. I was so disappointed with curls, I reached out to customer service to ask about a refund. I didn't want to pay shipping and restocking so i decided to live with it until another option comes available on the market.
