My oven arrived on time, and works well. I didn't think I would like the dial knob for inputting the cook time, but I really wanted a convection oven with microwave in one unit, so I decided to get it anyway. I actually like the dial! No more multiple number input on the keypad - just dial in the temperature (for convection) or time (for both ovens). I've baked two pies, one batch of cookies, and a pizza in the C-Oven, and it worked well without heating up the entire kitchen! The MW-Oven works well too. I'm really happy with the product. My particular machine makes a loud clunking noise (the fan, I think), but it is being swapped out for a new machine this week, and I believe this to be a defect of this one machine only, not an global problem with the design.
