This product only worked for about 15 minutes and died. I could not turn the lawnmower back on and have tested the exttension cord I was using. The extension cord is good. I have called Black and Decker and they instructed to to a repair shop which is an hour from my house. I called them and they gave me a hard time because I bought this item through Amazon and I decided I did not want to deal with a company and drive an hour each way that was giving me a hard time on the phone.I contacted Black and Decker again and requested a new lawnmower. I told them I was afraid that this was a lemon and I did not want to deal with the repair shop because of their attitude. I thought the product should have preformed better. My problem has been escalated and I was supposed to receive a call back from managment yesterday and I am still waiting for that call. I have a bad feeling about this.
