My Brother begged me to buy one after he got one for Christmas OH SO glad he did! I don't really care how it works but it WORKS I used to change my blade every week ...maybe ten to fourteen days I amnow still using the same blade on a "Disposable" razor after 100 to 120 shaves I never would have bought this without my Brother's recommendation so now I am passing that on......HEY I should be on commision I know! Seriously it just works! Just buy one and add your comments.
