One of the features I was most looking forward to was the probe; however neither it or the oven user manual were shipped with the ovens. The manual never has been provided, but the probe was sent. What a disappointment! The probe is wildly unreliable to the point of being unusable. I now rely on my instant-read thermometers. I also find that the preheat time is much longer than my old oven. The best feature of the ovens is the display.
