I have one. Used it for my first year and a half of rifle reloading for .223 and .308.
It works well but the trim to length you have to watch.
You basically have a pole screwed into the trimmer which stops cutting once it rests against the case bottom....the screwed in pole can slowly change length and start cutting cases the wrong length.
Ill make you a heck of a deal on mine if you want it....let me know.
