    I purchased this microwave from a local dealer when outfitting the kitchen of our custom built home. I wanted a compact, flush mounted, under-cabinet microwave. To the best of my knowledge, this was, and still is, the only brand that offers a 12" deep model. Two of my family members had this same microwave and liked its features and performance. If you have not already committed a space for this microwave, please read other online reviews. I agree, this microwave has great features and I like the way it cooks. But please be aware of a couple of issues reported by many reviewers, both of which I can attest to. Briefly, the door latch does not work properly and the white interior finish peels off. After a couple of years of use, the door latch on my oven started being "quirky". Sometimes the door will open and sometimes it takes a few tries. At least it is still functioning, unlike some owners who reported total latch failures. When my oven was about 5 years old, the white finish on the inside of the oven began bubbling, a little here, a little there. Now, at 7 years, the paint is coming off in big flakes. There is also evidence of rust on the inside of the door frame. I suspect these are related to inadequate ventelation resulting in excess moisture building up during cooking. When I open the door, I often see droplets of water on the "ceiling" of the oven. And, yes, these problems surfaced after the warranty period was up. Since my cabinets are configured to fit this oven, I am stuck with it. I have been looking for a replacement, but this (and the GE JEM25) are the only make/models I can find to fit in the 12" depth of the upper cabinets. There are 15" deep microwaves, but they would not have the nice, flush mounted look of the Spacemaker. I hesitate to purchase another inferior product, but I may be forced to take my chances if I want to keep my present installation. Don't be lead astray by the brand name. I don't believe GE did its customers any favors with the Spacemaker line. Read other reviews carefully before purchasing one of these - or purchase several, so you'll have spares!

  • Replacing one that died.

    I bought this microwave to replace a built-in Spacemaker, so I was limited in what would fit. This one fits perfectly. I would have preferred a higher-power replacement, but couldn't find one to fit the space. I was concerned about delivery of an appliance, but it came with my regular UPS delivery, no problem. I am very satisfied with this purchase.

  • Good

    We have a very limited space for a microwave oven and this is the only model available. It works fine but the door does not open well. In order to release the latch a second hand is needed to lift up slightly on the door. seems the weight of the door is slightly too much for the latch. Other than the latch the oven performs very well.

  • Great wide spacesaver

    We remodeled our kitchen around this microwave model 15 years ago. Then it broke last year and I haven't been able to locate it anywhere - but one night I saw it on Overstock (it's an amazing website, right!?!) and there it was! I hope this one lasts another 15 years.

  • Great Microwave

    Bought this GE microwave to put on custom built bottom cabinet shelf. Fits good and better yet it works great. Have used mostly for warming leftovers. No problems. Plenty of power. Especially like the 1 to 6 minute instant high power number entry. Had microwave for two months.
