I picked this along with the HS seated leg curl up off OfferUp to use in my knee rehab. Mine were from 92 and still looked awesome but just shows that HS equipment is built to last. The unilateral design is where this shined for me. I believe each lever arm is 4 or 7lbs then the holes near the bearings allow you to adjust the starting position. I was able to load my left leg as normal then start with the lever arm along with setting the starting point higher until my knee got stronger. For single leg/rehab this is good piece but is a space eater. Like Kieth mentioned, this is pretty pricey new but this version pops up on the used market from time to time. The single bar version is a different story. Overall this served me well and it’s what you’d expect from Hammer Strength.

It’s a solid piece but I think hammer missed the mark of a home run by not being able to tie the two independent arms together with a bat or a lock. If using both together I think a slow tempo is the play, but I do appreciate being able to go single leg without the weird “where do I hang my other leg” feeling like I have on the piece in my gym. If I found one, I’d be making the one minor modification

Kind of a unique machine. I always preferred just doing 1 leg at a time because trying to keep each leg in sync doing the at the same time gets weird

I really like this unilateral quad extension. Very expensive if bought new, but good piece to find used if you have the space. The single leg aspect is a bug win. I have used this over a dozen times at the gym I go to when I’m working in Albany.
