Yes, I recently tried Bic Chrome Platinum blades in a Gillette Slim Adjustable with terrible results. The blades were part of a sample pack from tryablade.com. I was afraid the first blade was going to shred my face, but I stuck with it long enough to make it through the first pass. It felt like a jagged edge. I tossed the first blade and waited a couple of days to try blade #2. I didn't even make it through the first pass before quitting and throwing it in my sharps container. I completed the shave with another razor. I don't know what the deal was. The blades didn't look any different to the naked eye. I've read they're well respected but they didn't work out for me.
