I'm too afraid to try them. I don't like rolling the dice on my quilting purchases because I can't get out and get replacements very often. Too many people have reported iffy quality on them. I'll pay for my Fiskar blades. They are incredibly sharp. They slice through fabric with the greatest of ease. And they cut through an unfortunatly positioned thumb like a hot knife through butter! Yep, I've got the scars to prove my blades work, so I won't be looking elsewhere :)
