Product out of the box did not have all features working correctly. Broiler did not work in a usable fashion, cycles on and off at random times. Hi power burner control does not work correctly, only provides about 30% power in all three HI detent positions. If you turn it back to about 99% then you get full power. Left rear burner control not linear, you get about 30% power at position 7. The 3 ring Hi power burner control is very hard to use since there is low resolution on the dial since each of the 1, 2 or 3 rings occupies only a third of the dial. Hi power requires maximum resolution. Should have had a 3 position switch to select 1, 2 or 3 rings and a full turn dial for power setting. Not a good design. Convection oven fan cycles on and off. Needs to run all the time for consistent performance. Not a good design.
