I love the low temps the oven has and it cooks nicely; however I wish they had put a louder buzzer and one that would continue to buzz so that it is not missed and the food burned. Also it would be nice to have a separate light in each oven.  The low temps for warming are the most awesome part and the reason that I picked this oven above all others (it is a rare option to go as low as 140).  You can dehydrate in this with convection and they don't advertise this, but I have done it with good results.
