I’ve had this unit for about 3 years. I love it. If there is a negative to the unit it would be that it takes a little longer to get to temperature set and a little longer to cool down in the oven side. The microwave is great. There has been a few times where it would not start. After opening and closing the door a few times it would start. I think it is the door switch. I did purchase it online, at the time, and got a terrific price. I had to have this exact size to fit my existing space. There were very few brands and models to choose from. I would purchase the same unit again.
