These blades cut great.  Nice clean cut on veneered products such as the side of a cabinet, etc.  Only downside, and maybe it's just with my Festool jigsaw, when ran at high speeds (cutting) these blades make the worst high pitched noise you've ever heard.  I can't even explain the sound but if you don't plug your ears it will literally make you brain dead.  You can feel your ear drums resonating in your head!  And again, maybe it's just my saw or my ears but it's painful.  If I am only making a 5" cut with this blade I will literally walk off the job site to my truck and get my ear plugs.  It's that bad.  Other than that the blades cut great!
