I don't have one now but when my kids were growing up I had one for them. It would only start when using a timer and would shut off on its own. My daughter can burn the best pot of water so she was never allowed to cook on the stove if I wasn't home so this was my way of keeping my house safe for all of the kids. I didn't worry about them setting it and forgetting it because the timer would go off. You'd be surprised how many times I'd come home and see where there was food in the toaster oven that they'd set and forgot and if it hadn't been setup to have to use a timer, it would have been burned and so could of my house been burned. They are good, I had one yrs after the kids left. I made sure it was big enough for a small pizza to fit into so then I knew it would handle everything I needed. It went bad and I just never replaced it.
