This not a "toaster", its an oven. This thing is a complete piece of garbage. It is impossible to not burn toast to a blackened lump of coal unless you stand right in front of it and monitor the entire process. Once you figure out where to place the timer, it is impossible to get it back to that exact point given its poorly thought-out design. Get something with a static thermostat.
