These blades seem to get good reviews from wet shavers, but I have tried the nacet in 2 different de razors. and just get a scraping , dragging feeling. I didnt end up with razor burn or any weepers, and I got a nice clean shave. Just not a comfortable shave. Used them in a e&j de89 and a 56 gillette tto. Maybe I just move these back with the derbys and dorcos. Save for emergencies or scraping glue off of something
