Rated 5 out of 5 by from This product has great features.... I have been using our microwave for several months now and am very pleased with it. The product has great features and is very easy to use. It blends very nicely with our other appliances. It is so easy to keep clean.

Rated 5 out of 5 by from This microwave is the perfect size and has a clean design. I searched long and hard for a microwave that would fit into a 23" space but I needed something larger than most of the countertop microwaves that I found. This one is the perfect size. Clean design is important to me, and I needed it to coordinate with a variety of appliance brands in my kitchen. I like that the logo is not huge and contrasting with the unit. This Whirlpool looks great and works well. It is easy to keep clean and the numbers and labels are easy to read.

Rated 4 out of 5 by from Cook times are accurate. First time I have had a microwave that the baked potatoes are done at the end of auto time period I had to look hard to find the bisque color. I really like the performance of this microwave and all the bells and whistles on this product.

Rated 4 out of 5 by from Engineering tried, but removed old options that were functional. Bought this product to replace an old version of it. New features may be fine, but some of the old features were not carried froward to this model. :-( Otherwise it performs better than the old model.

Rated 5 out of 5 by from Great microwave! This microwave was an amazing replacement for my nearly 18-year-old microwave! Though I was looking for one a little larger, this microwave more than compensates in power and ease-of-use. I would definitely recommend this product.

Rated 5 out of 5 by from A little surprised I'll admit I bought this because when I moved into my new townhouse a microwave wasn't included. I bought this because it matched the rest of the kitchen applicances. I am amazed at power of this product. My OTR that I had at my previous place couldnt match the cooking/heating power of this unit. It has all the typical features of a standard microwave and all of them work well. No disappointment here, Highly recommended!
