-standing and laying leg curls feel really good. laying feels super isolated.
-Leg extensions feel nice, I'd say the only downfall is the lack of adjustment for the backpad which doesnt allow optimal knee placment. but you can easily adjust around it.
-positives: pretty cheap, i fit in it well (6'1"), alot of adjustability, relatively compact, feels really solid, instructions pretty straightforward, received quick.
-cons: no back/forward adjustments for backpad in leg extension mode. pads are pretty squeaky.
