I love this Kenmore micro wave oven that was given to me last year. I believe since it was manufactured in September 1992, has a lot to do with it having the simplicity of using it like it does. I find it challenging enough in today's world of new technology at my age to have to try to figure out these newer models of micro waves along with everything else. So my oven, although it is old by some standards, has me jumping for joy that I have it. It works as if it is brand new even for all that age the oven has on it. The only reason that I did not give it a perfect rating on the heat distribution is because some TV. dinners don't heat evenly according to the time given in the directions. I'm not really sure that is a flaw of my micro wave oven to be cocerned with as I have never seen a micro wave oven to cook evenly perfect all the time to every cooking time directions. I would strongly recommend this type of mirco wave oven to all interested with wanting one with an ease of use and one that has durability.
