convection, fast boil, warmer etc. all work well. like how the digital display shows each degree difference as it heats. top has not been a problem to clean since i clean it daily and thoroughly. wifi app - every time the oven is touched it sends a message to my phone......and tv!  found it annoying and i won't use it so deleted. also, i had app open on my phone and was doing something else on my phone and accidently turned the oven on! luckily someone was home to notice. more my fault than products. anyways...it looks good, cooks evenly and the fan isn't loud at least in my opinion
