We've had this since 9/28.  Delivered as promised.
Does NOT have an operations manual - you have to download it.
We are NOT sure if this is convection oven.  Food comes out overdone even tho we put the correct time and temperature.
Oven DOES NOT have extended warranty.  I asked for one when we bought it and was told Samsung does not offer extended warranty plans for their electric ranges.  Why?
We should NOT have to call Samsung to get an operation manual.
