Not as powerful as our 20+ year old GE Profile it replaces. Cooking times for both the Air Fryer and Convection Baking were not accurate; for example, frozen patties called for convection baking time of 20 min @ 450 but the food was NOT cooked and had to be put in for another 15 min before fully cooked.... Had the same problem with the Air Fryer with chicken tenders.  GE as also gone cheap by not providing a decent operating manual; had to download a woefully inadequate manual from the web site.  Frankly, I expected more from GE!  Furthermore, it's too costly and somewhat clunky to operate!  You can't select a cooking power for a time seeing of less than 30 seconds, which can cause some foods to overcook when all you need is a little more heating time.
