The microwave functions well.  The main reason I didn't give it a 5 is because there is very little information on how to use it.  It says access the full instructions from the web site.  I have yet to be able to get them.
The convection oven feature is nice.  Still don't know what "Combination Fast Cook" is or how to use it.  Same with "Air Fry".
Not being able to punch in the numbers is a big adjustment.  And not being able to set a time other than increments of 15 seconds isn't very convenient.  I have to stand and watch it and stop it for the amount of time I need.
My old microwave (different brand) had some quick buttons that I used and this does not have them.
For the functions I do use it has worked well.  I've had it a little over a month and am still learning.
