Product review (2 stars): Don't use the self clean unless you want to brick the range.
I didn't buy this off Amazon, but beware.  This range has some serious issues if you use the self clean cycle, and there's plenty of complaints on the Samsung community web site.  Control panel goes dead, and door stays locked and won't open.  I've had three technicians to try to repair, and it's looking like this 2 year old range is going to have to be replaced.
