So far so good with this new and smaller combination microwave oven bought as a replacement for three larger models (identical to each other and now, apparently unavailable) which died on me over the past few months! Large enough for us, and so far, like previous Sharp microwaves I`ve had over MANY years, before the aforementioned disasters, works perfectly. Only one tiny quibble - the previous models had a very useful "Short-cut" button for exactly a minute`s operation - shame it couldn`t have been incorporated in this model - however, that`s really just a minor quibble. As I said - so far so good - and we love it. Another advantage is the nice loud "beep" when it`s completed the job - even my very deaf husband can hear it from the next room. Another useful function is the facility to just press the "set" button for an extra 30 seconds of power without having to completely reset the program in the event that things aren`t quite hot enough. I can thoroughly recommend it.
ADDENDUM: - I discovered, quite by accident, that the little "start" button actually switches the microwave on for 30 seconds if pressed with no other commands. Even more useful, in my opinion, than the "short-cut" button I was bemoaning the lack of! Not too impressed with the manual that comes with the machine - it seems a bit hard to follow and the print is tiny. Far better to download the manual from the Sharp Electronics site and print it yourself - there aren`t too many pages to print. I rather wish it had a proper slide out shelf instead of the round one that stands on the turntable, though.
