I have had this for about 2 years and yes, it has been used! It fully works however and is in excellent condition apart from the stone, but this is what happens to them with use! As you can see from the pictures it works 100% and makes a good pizza! Newer models now come with a black stone which, for visual appeal makes more sense after they are used. If it bothers you that much, you can order a new black stone for about £20, undo 4 screws, remove the old and fit the new. The stone does smoke a little when it gets hot. Comes with metal paddles. Selling as the missus has bought me a fancier one.
