Product Reviews
Rated 4.3 out of 5 by 31 reviewers.
Rated 4 out of 5 by Exactly as represented Exactly what I wanted and needed. Delivered promply. Works like it is supposed to. Thank you! 11/4/07
Rated 3 out of 5 by Very good This product is less powerful than the Kenmore that I had. I used to do 30sec to my tea with the Kenmore, now I need 1 min with Whirlpool. Hay, I'm not in a rush! They need the improve the shipping package. The unit that I received was crushed in the back, really bad, but I place the unit inside a cabinet so that is not a big deal. 5/22/07
Rated 5 out of 5 by Excellent service I ordered this microwave as a direct replacement for the built-in unit in our house, so it was very important that I receive the exact same model microwave that I ordered. The model shipped was the correct model & took less than 15 mins to install. 12/15/09
Rated 5 out of 5 by Easy on the Easy I was distressed that the microwave which this machine replaced suddenly "went south", with sparks aflying and smoke asteamin'. But I located a replacement oven with fair ease at AJ Madison and ordered it accordingly. It arrived when it was schedule, and it was exactly what was ordered. This is not my first AJ Madison purchase, nor do I expect it to be my last. These folks have it together, for sure! 1/9/10
