Review title is Not a good replacement [SEP] My husband mentioned his razor didn't seem to be shaving as well as it used to, so I ordered this replacement head for him. It didn't shave well, so I tried to return it. We got it back with "No such number" on it. This is on a label I printed from the return authorization page, so I couldn't have made an error on the address. I DO NOT RECOMMEND BUYING FROM THIS SELLER.
