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.

With a vintage opening of 25", my options for my kitchen were limited. I thoroughly researched my options and am very pleased with my decision to purchase. The knob control in lieu of traditional numbers of the microwave does take some getting used to. Aesthetically and functionally this is a very nice oven/microwave combo. My opening was 48" and with this unit being just over 41", I installed a piece of stainless steel (cut to match) below the unit.
