The best feature is the double doors because it’s so easy to open and get to the inside from standing in front of it instead on the side of it.  The racks are awesome and so easy and smooth to move.
I’ve only had it for 3 weeks and haven’t used all the features but what I’ve used are the best.  The air dry was tested on day old French fries and came out as good and crisp as the day I got them.  Have used the probe and the pork roast was cooked to perfection.
Love love love it!!
