Query: Dependable shaver

My Norelco has been in service for over ten years without problems. It is used daily and has never failed. After eight years of use I did send it out to have the battery replaced. I guess you can only recharge these batteries so many times. With the new battery I can expect many more years of dependable service. I highly recommend the Norelco shaver.
