My former microwave stopped working after only 4  1/2 years. This new LG is  a gem and is stainless steel, matches perfectly with all my other appliances. It is really sturdy and looks soooo good above my range. The installers did not take much time at all to help explain how to use the microwave. I felt a little lost the first few times trying to figure out how to use the microwave. I'm not a believer in "wifi" usage of the microwave. My needs are simple and after playing with the LG  I learned the basics and I love it!! I recommend whoever writes the informational booklet to keep it simpler to read and less details.
