Kenmore Elite 2.0 cu. ft. Countertop Microwave with Sensor Cooking Controls Review

I recently purchased the Kenmore Elite 2.0 Microwave for several of its neat features.  Having researched for a reasonably priced large capacity micro for large casserole dishes, ease of use, and the ability to be built-in with the optional trim kit, this oven seemed our best buy.  I also wanted an appliance that could be serviced from any location in the USA. 

 I didn't have the opportunity to use its many features which includes a round cavity which would allow cleanup to be easier.  The micro blew after only 3 days of use.  It made an unusual noise and stopped working after emitting a cloud of electrical smelling smoke.  I don't know if this is a general problem or isolated to my microwave.  We were able to return the item for a full refund but only after the customer relations representative physically tested the micro to see if it really was inoperable.  This was not offensive to me as I realize there is a problem with people buying, using for a specific event, and then returning the item. 

Rating it is difficult since I did not get a reasonable amount of time to use it prior to its malfunction.  My husband felt we should not give the Kenmore Elite another try.  Since it blew, I am blue!
