Product review (3 stars): Lot's of bells and whistles but they are not worth the price!
After having used this range for a year and a half, I feel qualified to review.  I purchased it because of all the extra's and have been disappointed with these.  The large sturdy knobs for the cooktop are easily turned on by accident.  I recently returned home to find the cooktop turned on and hot.  My husband said he had made a sandwich several hours earlier but didn't use the stove.  He must have accidently bumped the knob and turned it on.  Also the icon for the warming drawer is so sensitive that it gets turned on by wiping the stovetop and letting the dishcloth edge drape across the icon.  There is a control lock for the oven and drawer but it also locks the oven door so I never use it.  I would like access to the oven when the controls are locked for cleaning, etc.  The temperature probe never worked.  When I first tried to use it, it would signal and turn off the oven after only a few minutes cook time.  I thought this was due to the roast being so small that the probe tip was not in the center of the meat. The probe is about 5 inches long and must be completely inserted in the meat with no part exposed.  Hard to do with a small roast.  Today I am cooking a 21 lb. turkey so I could fully insert the probe.  Still, it tells me it is done after only a few minutes cook time.  After 30 minutes on the phone with Samsung customer service, we decide there is definitely a problem but she says it is out of warranty.  So I have a worthless temperature probe after only two attempts to use it.  I love having the small upper oven for everyday use.  It heats quickly and after I learned a few tricks, it cooks well enough.  I preheat to a temperature 50 degrees warmer than I plan to cook and then turn the oven down 25 degrees lower than called for when putting in the rolls or whatever.  That helps prevent the top from over browning. You cannot standard bake in the upper oven, only convection.  The lower oven will do standard bake but doesn't top brown at all so I seldom use it.  It is useful as a "keep warm" oven when baking in the upper oven.
I never use the warming drawer or the top "warming center".

The range looks good and I carefully use my cast iron cookware everyday. I have a few minor scratches on the cooktop after 1 1/2 years use.  The cooktop is very slow to heat up, even the "fast boil" section.  If I had it to do over, I would look around for another range.  For less money, I could have had a stove with fewer features, since I am not able to use the features anyway on this Samsung.
