We've had this product about a year now and have had the chance to explore the features a time or two.
To be honest, 95% of our use is that of the microwave, reheating, defrosting etc. Having the convection oven option has been useful on a couple of occasions. Family dinners for 16 to 20.
The bottom line is, it's a little spendy for a microwave but  I will use, the convection oven more often to make our purchase more worthwhile.
Very good quality
