For the first six week, I thought the over was great, until I tried to bake at 450 degrees and then all heck broke loose. Using my K probe thermocoulple oven never got about 350 then starting dropping.  Also the oven would not let me set an internal temperature using the provided probe.  Yes I rebooted.  Repair person arrived told me it was the "motherboard" which had to be ordered.  Wrong parts arrived technician tried to correct the issue had to order the correct parts. Time will tell. Would not recommend oven.
