Bought this to replace its parent / combination microwave (1st generation @ 1500 watts that I had since 2008) and it does not work as well. All functions take twice as long to heat / cook, no electrical power saving (watts is watts). Back to using my gas oven to cook. If the parts to keep my original unit were available, I definitely would have been better off to repair it than buy this. What ever happen to products improving over development, rather than make them 1 year throw aways. Space saving is the only feature valuable.
