It's just so odd that you can set the microwave for, say, 20 seconds.  It goes from 15 to 30 seconds.  They say you can set it for 30 seconds and then turn the knob to 20 seconds, but it never works well.  Just annoying.  Other than that, it's a good unit.  Love that the microwave is also a convection oven.  Wish it had a small broiler, too.
