Question: defrost mode ?
Document: I have not yet tried to defrost anything, but will update this review if I have more feedback.LONGEVITY:Lastly, I'm hoping this microwave will last for at least 8 years, especially since it costs many times more than other models.
We replaced a Panasonic commercial microwave with this sharp. The build quality is a lot superior than the panasonic. The only concern is the light works and sometimes doesn't work. Not much of a concern to us.I would definitely recommend this microwave.
We love this microwave! Put in food, close the door, turn the knob and it works. No buttons to press and no removable rotating glass tray to clean. We've had this for about two months and have had no problems. There is no temperature control though and the maximum time is 6 minutes.
We have about 10 in the building and they work well and easy to use.so when we need to order more it will be the Sharp model. it fits on all the counters we have in our break rooms, we have been buying the Sharp Microwave for many years.
Very pleased. Only issue is that dial markers can be hard to see when selecting cooking time. There isn't a cooking time display above dial as shown in the Amazon product picture.Update 9/6/13 - All units hospital and mine still operating without any issues.
Very nice unit. We are using it in commercial environment and are quite pleased with the performance. Would purchase again.
This isn't a complaint; just remarking on a &#34;feature&#34; that isn't useful to me.It has no rotating plate on the inside. That makes it really easy to clean. Easy to clean = likelier to clean it, which is a serious problem in my household.The handle feels a little cheap. The button on the inside is plastic and it just doesn't feel as sturdy as I would hope from a &#34;commercial&#34; microwave.
This is my third microwave purchase in the last 15 years, so we purchased it primarily for its simplicity hoping for reliability. The family was very concerned:--- Could we set a time exactly? Yes, the dial has little clicks which allow you to set 30 seconds just as reliably as if you actually typed 3 - 0 - start.--- Could we operate the door easily? Yes, the door has a latch on the back of the handle which you squeeze to open the door.
This is a plus since it gives me the option to heat things that require low heat like bread, without the risk of over cooking it. For things that require more heat, I just heat it longer.The food appears to be evently heated, so we are not missing the turntable.It lights up when in operation, although it's not easy to see inside the window. It does not light up when the door is open.
This is a great microwave for the person who does not want all the whistles and buzzers.
Answer: No defrost mode - just more or less time at full power. A great microwave though.
