Does anyone NOT recommend monolifts? The reason I ask is that, based on reviews, they are highly recommended. However, I am constantly seeing used monolifts on sale (particularly the Rogue version). When someone attemps to sell a used item, you automatically ask yourself; is there is something wrong with it? or was the buyer not fully satisfied? etc... I like the idea of not having to step out during squats, or not needing a lift-off when bench pressing. I think it would do wonders for my joints. Anyone, please chime in.
