Not the best. Our Furrion convection/microwave is fine, but has worn the switch holder (latching mechanism) and started blowing fuses. It was warrantied out by the manufacturer. The only way to cook evenly in convection mode is to use the turntable and round rack.
My wife had me remove the Furrion cooktop and gas oven altogether (the oven was useless). I am installing a convection cooktop and will turn the oven space into storage. We will continue to use the Furrion convection/microwave until it dies again (with the turntable and round rack) and replace it with a Whirlpool when this one dies.
