This GE combo microwave and oven works beautifully and looks even better. It’s a sleek, modern update to our kitchen and really elevated the space. Both the microwave and oven perform perfectly — everything heats and bakes evenly. The stainless steel does show fingerprints, but that’s expected. Overall, super happy with this purchase!

So far I love this combo unit with one exception: The oven vent is right under the oven door and all the heat blows out from there making the kitchen very warm. That is a benefit in the winter but not so much in the summer. Other than that, it's perfect! Even though they are the same size, 27", this combo unit doesn't take up as much wall space as my previous wall oven/microwave and they had to install a filler panel at the bottom. However, the interior space on both units is larger than my previous wall oven and microwave and a regular sized baking sheet fits inside now. Other reviewers complained about the fan being loud and staying on for a long time after finished cooking, but I don't find that to be an issue with mine. The oven does take a little longer to preheat, but that's not really an issue either. Overall, I'm very satisfied with the purchase.

Beautiful with great features, but we have had it for almost 6 months and discovered that it is running up to 50 degrees hotter than the temperature shows. If we can correct that we would happily provide a 5 star endorsement.
