A very versatile piece of equipment, and I'm glad I got it since it saves a ton of space. I got it pretty early and it was a chore to ship it to Europa at the time, since they hadn't set up international shipping yet.
I use it weekly for leg extensions or lying leg curls. I wish seated leg curls would work easier, but you need to flip like the whole attachment, and I got no time for that.
Biceps and triceps work also work great tho you really need to find your ideal lever position for it to feel good there I find.
My real gripe comes with the build quality and some design choices. For one I do not trust the seat to hold a 200lb lifter you does some heavy leg extensions. I prop it up with an incline bench to be sure (that also allows me to get some extra stretch in my quads by doing lying leg extension). It flexes quite a lot if you have at least like 80lb of weight on the arm. The leg pad is also slightly askew no matter how you tighten the screws.
My biggest issue is with all the pop pins for fixating the attachments and that they hold those right on the corner of the hexagonal piece. That really eats into the pop pins and just makes handling a drag over time, since it gets hung up on the thread and you really need strength on to tighten or loosen them. we also have the issue that one of the screws for tightening the attachment on the 3x3 post broke it's thread and now we can only fixate it on 3 without being able to fix it. The only reason I don't give it a 2 Star on build quality is that it was from a price point quite good I think. It sounds rude maybe but with a lot of stuff from Bullet Proof, I wish there was like a Rogue design team there to steer it more towards bomb proofness instead of it being almost a bit flimsy feeling for just being a miniscule bit more versatile.
