Hack-Squat Machine

[justins18]

What is everyone's opinion on the hack-squat machine for isolating legs? (Not the possible knee-joint complications or lack of back-involvement... simply for it's effectiveness on building legs considering that one uses good form, going low and controlled).

i think it is a great machine, kills my knees though, i do squat one week and hack the next, works well for me.
