Satisfied purchase!

I have been looking for a low profile microwave for a couple years now. As our kitchen cabinets above the stove are not high enough. I am so glad I found this microwave because not only does it match our stove perfectly, it goes great with the kitchen. Feels nice to have a microwave off of the counter that actually heats our stuff quickly and doesn’t take double the time.

I really like how easy he was to install and the slickness and the build of the microwave. Took Me in another person about 20 minutes to install. The product was packaged well.

The 30 inch slim over the range microwave is a great choice for our family. Easy installation and user friendly controls. The unit also very quiet.

Wonderful upgrade to our kitchen

This is a replacement for a ten-year-old OTR range. I really enjoy the brighter lighting provided by the LED, and am able to better see the surface of my range (I am 6’4” tall, and the slimline construction improved my line-of-sight). The microwave controls are very much like the Electrolux it replaced and required no learning curve. It is solidly built and a wonderful addition to our kitchen.

Quiet, powerful Microwave

I love this microwave! We have really short ceilings (I’m 5’5″ and I can touch the ceiling), and I do a lot of canning with a tall canner, so it was important for us to find a short microwave hood. This one fits great! I do like the LED lights, they illuminate the area nicely. The vent is much quieter than my previous hood, and seems to evacuate stinky smells much quicker. My daughter absolutely loves the auto-cook button for cooking potatoes in the microwave. I don’t know how it does it, but the sensor works very well. Cooks her potatoes to perfection very quickly, every time! Love it and highly recommend this microwave!
