1) Was concerned when installed did not come with much in the way of instructions. But after reviewing panel the process is quite intuitive and is easy to operate.
2) The real test is time will it continue to perform as well as it is performing now “new”.
3) I was accustomed to my older unit and though it was state of the art when I purchased it 8 years ago but I now realize that GE has continued to improve and upgrade there products all the time. 
4) With the COVID 19 I was unable to go to various stores and do my usual shop and compare process.  Instead I called my local trusted retailer and asked for the best product for me.  He said he has seen the gambit of units and had purchase for his home the GE profile Microwave.
