Well I've had two different kinds. First the harbor freight version and it worked pretty good I thought. Blades didn't last that long but it seemed to do the right thing. I decided I'd get a Fein one day when Amazon had em on a real good sale. There is little comparison between the two. Both do the same kind of work but the Fein is way ahead of the HF as it should be considering the price. Their blades last a lot longer too.
I once heard that cats and women will do darn well what they please and that men and dogs would do well to accept it and just go on.
