Review on 🪒 PHILIPS SH90/70 Replacement Blades for Series 9000 Electric Shaver – Enhance Your Shaving Experience by Adam Smith

removed old blades and blade holders and then replaced with new All-in-One/72 replacements. Seemed to fit okay. I shaved it once and the replaceable head started hanging out. I took a closer look and the new head does not sit flush with the base. You can't get the entire interchangeable top flush with the base. A corner always sticks out. Net: It just doesn't fit my s9000 series shaver. (No, you can't just take the blades out and put them in your old top. I've tried). I am returning a used /70 to Revain and will be contacting Norelco to see how they intend to resolve this issue.
