Many people favor built-in microwaves for their kitchen, as these save counter space and are easier to access. Built-in models are typically very large and powerful, with at least 1.5 cu. ft. of space and over 1000w of power. They also cost more than countertop microwaves, with prices for these units averaging at around $530. This high price tag has earned built-in units a lower-than-average value rating. Users also find them to be less reliable. However, as far as performance goes, built-in units do a better job than average at heating and cooking food evenly.
