Very nice for the price. Well built and solid. Nice home leg machine. I put it together in about 45 minutes, but I have nice tools. If you are using the wrench that came with and are not very handy, it might take an hour or so, but it's prety easy to assemble. I like it and use it every day. I am 82 BTW, and still working out as much as possible for an old relic.

This is a decent piece of equipment for the price! Easy to assemble and seems sturdy enough. Has a slight wobble but once weights are on it it’s not really noticeable. The only issue I would note specifically is the seat depth (front to back) is very short - when seated upright it’s small for even me (5’4 female) and my 6’ boyfriend won’t be able to use it upright which forces a lean-back just to do basic leg extensions!

Love this leg extension machine. Well-made, easy to assemble and works perfectly. I can certainly "feel the burn". Could not be more satisfied.

Not a bad product but the packaging could be better. The bottom edge of the seat cushion came crushed and has not returned to its original shape. Doesn’t look good but functionality is not affected.

This J10 leg extension and curl machine is a great addition to my home gym. It’s sturdy, easy to adjust, and allows for smooth leg extensions and curls without taking up too much space. Assembly was straightforward, and the padding is comfortable even during longer sessions. It does exactly what it’s supposed to do—excellent lower-body isolation at home. Highly recommended for anyone serious about leg training without going to the gym. 💪

Pleasantly surprised by the quality of this for the price. I was kinda expecting it to be somewhat flimsy and that I’d be returning it but it’s nicer than I thought. I’ve only had it a short time but as long as it holds up I’m a fan
