I am using Samsung CE117PF-B microwave very handy kitchen appliances. The best feature of Convection cooking is that it has a third heating element and evenly distribute the heat for a perfect cook. It has smart humidity sensor and 200 Indian menus. I advise you to give it a YES with no doubt, it is best rated over the range microwave convection oven.

Kenmore is still the most popular.
