Title: Defective parts ruin a great design
Review: The oven works perfectly when new. Actual temperature is exactly as shown on the temperature dial. As the oven is used, the thermostat distorts. Temperature is lower and lower and lower, actually changing a bit during extended use. The oven, used twice a week for one hour each time, now heats to 300 degrees when set to 350 degrees - and temperature drops if the oven is used longer. This seems entirely due to use of a cheap thermostat unit that gradually distorts during use and that never returns to original shape. Thus the unit will require a good oven thermometer to compensate and monitoring at all times - an intolerable situation. do NOT buy this oven.While the physical design is superb, the thermostat's gradual cumulative inaccuracy makes this unit undependable for most purposes.
