I bought the Squatober orange edition. It's nice and smooth and gets the job done. It might be nicer to if this could attach to a pulley, but I'm not sure how often I'd actually make use of that.
My daily driver, and an excellent bar. The black zinc has faded over time and the bar is now a brownish hue, but that's purely cosmetic. The knurling is aggressive enough without tearing up my hands. No complaints.
