I have what I think is the Husky branded one - looks a lot like the Oregon, but I'm not real sure. My first attempt to use the damm thing was less than inspiring. First off, the thumb screw you tighten to secure the contraption to the bar had rolled-out thread ends, not machined, so it had a skewed tip - impossible to tighten down without the whole mess wobbling out of alignment. I wound up flat-grinding the butt-end of the screw to smooth-out the installation - a good bit better but still omething that should have been done before it was packaged. Next, I noted the stamped steel chain-holder-downers don't do a real good job of holding the chain stationary- -it flops side-to-side preventing a consisten angle unless I manuall hold the chain. Bar grooves are OK - I'm not talking a LOT of movement, just a ton more than I'd expect from a jig designed to produce consistent/precise filing.
