While the oven works well, there are certain peculiar design flaws. The timer feature, for example. The timer can only be turned off by turning off the oven. You can't reset the timer after each cookie sheet without turning off the oven and restarting it. This is despite the kitchen timer button saying "on/off" and the manual saying you push the kitchen timer button to turn it off. The service technician said, no, that is just a design flaw. The probe is also a poor design. If you plug it all the way in, it doesn't work. It must slightly out to function. Again, the service technician said it was just the design. Now, perhaps the technician is wrong. Nevertheless, it is two problems with the oven from the day of installation. Not a good start. At least it cooks well and is otherwise satisfactory. For the price, I'm not impressed.
