I got these blades to use in a "Rockwell Bladerunner" saw.  They fit nice, cut good, and are a decent price.  They don't seem to be able to handle quite as tight of radius as the blade that came with the Rockwell for scrolling without the piece vibrating.  These blades are a little shorter than the blades that came with the Bladerunner but work fine for my needs.  If you are wanting to cut a thicker piece of wood you might want to get a slightly longer blade.
