Product review (1 stars): Horrible Oven temperature swing.
Bought this unit from Lowes 15 days ago.  Tried to cook about 600 cookies yesterday for the airmen at eglin.  The temperature swing was too great and could not get a stable temperature after 2 hours of warm up.  I was trying to get and hold at 300F.  The swing was 265 to 315F.
You can hear relays clicking often.  I thought technology would have prevailed into current ovens.  I replace this with a 1972 GE oven that had a swing of 10F. and no relays.  It should have electronic relays and a proportional temperature controller.  I guess after 40 years no new technology on temperature control.

I should have looked closer to its cheap regulation.  I can not understand consumer reports giving this great ratings.
