Tried to return a defective charger. I was told that since it had a nick in it, it was unreturnable. I was able to convince the manager to let me get an exchange. I now have an extra because I had to buy another before I could return the defective one. The manager said cords do not come damaged from the factory. 100s of millions of theses things are made, and they some how get 100% out without defects???
