I replaced my bulky, in the way, counter top microwave with this jewel. The nice black exterior, and the easy to use key pad were definately selling points. Once at home, I set to the task of installing this over the range microwave. The instructions were easy to read and follw. The installation was fairly straighforward, and should be easy for any part time handyman. The vent has three different methods of use for various applications, like if you have an external vent hood, or just want it to filter and return the air to the front of the unit. The mounting bolts were easy to position using the inclosed template, and the mounting bracket for the rear was the same. The template was straightforward, and easy to understand. It does take two people to mount this unit, it is awkward when mounting as well as heavy. Once installed it was easy to use and the 1500 watt power make cooking quick and even. I love this unit and would reccomend it to anyone.
