Review on High-Performance SH30 Replacement Heads: Ultimate Precision and Comfort for Philips Norelco Series 3000, 2000, 1000 Shavers and S738 Click and Style with 9 Blades Cutting System - SH30/52 by Victoria Snyder

I bought these for my Philips Norelco PT724/46 3100 shaver and couldn't believe how rough my shaver got after I installed them and the blades are so dull that sometimes they stop The razor stopped spinning because it couldn't cut hair. Along with the blades came 3 shaving heads that glide over the skin as you shave instead of gliding over it. I have had this razor for a long time and have changed the blades twice, never before have I seen a product that works so terribly. Very disappointed. You get what you pay for!
