What People Are Saying

Rated 1 out of 5 by from Not very reliable We purchased this product last summer and had only used it for about 6 1/2 months when it quit completely. Since we are senior citizens the appliance does not get used that much so it was very surprising that it malfunctioned after so short a time. I called your office and the lady told me to return it to the dealer (which was Home Depot) and they would replace the defective machine with a new one. The new appliance was only used for a few days and it started making a "rotating sound" that was never present before, both in the old one and this one. It is still functioning with the offending sound still present. We are now wondering what to do. If this is an indication of the reliability of LG microwaves, we are not sure if we want another.

Rated 5 out of 5 by from Best Microwave I have ever had I debated and researched a long time to find the right microwave and I am so happy that I purchased this product. I has a very easy to clean surface inside and the sensor cook technology is awesome so food is not over cooked. It has lots of options and the rounded inside cavity makes it nice too! Great on sale price!!! Definitely recommend this to anyone.
