Worked great with my Black and Decker jigsaw. Following the advice of pros on You Tube, I bought T-shank blades instead of U-shank blades because of the durability of my saw. Not crazy about packaging. Came with the blades loose in the packaging so they don't hold very tight. Also, the case looks like a CD case, but no matter what I do I can't get the hinges in place. They keep popping up. A little annoying, but not disturbing.
