I've had this about a year. It works fine for breakfast and stir fry but it lacks the power for items like smash burgers or searing steaks. I have not been able to get it up to 500 degrees despite 30 minutes of preheat. At 450 the temperature will immediately drop out of range when a burger is put on. It is not able to regain temperature as long as the meat is left on. I have been disappointed with the performance
