I was shaving my face with the SF3 shaver and felt a stinging on my face. I turned the shaver off and found two holes in the micro screen. I had a nice red "W" carved on my cheek from this shaver. I bought this shaver to replace a 20 year old Ronson shaver that has never given me any problems. I am still waiting to hear from Remington Products on this matter. This SF3 shaver didn't last a month from the date of purchase.
