Product review (1 stars): DO NOT BUY
I agree with everyone else who has said it takes too long to preheat, is too noisy, and once it arrives to the set temperature, it must be turned off in order to increase the temp.  I paid almost $2500 for it and have hated it since the day I got it.  Had a 25 year old GE that worked much better, just didn't look as sleek as this.  What I wouldn't give to have it back now.
