Summary: We replaced the first after about 7 years because we had our kitchen remodeled. We drove it 250 miles to our vacation house and it continued to work another 10 years!! So of course we bought another Sharp for our remodled kitchen and this lasted about 11 years or so until the plastic control panel broke and Sharp said it could not be replaced, but it still worked! However, since I was afraid of getting electrocuted etc., we bought a third in October of 2010.
Summary: On April 18 we placed an order for the above oven. The site stated there was 5 in stock. Our shipment day was to be on the 21st. We received an email stated that the warehouse was out of stock. ( I thought they had 5 on Hand) We were to receive this order on the 25th. When I called their customer service line the recorded message was "we are closed for the holidays" call back later. I called again today the 26. The same recorded message.
Summary: I purchased this oven about 17 months ago. It lived up to all of the hype and worked great. Last week it just went dead. I tried to get some help through Amazon and the supplier. Nobody responded. I paid for an online evaluation and was told it was probably the fuse or fuses. The only trouble is you have to remove it from its location above the stove to get at the fuses.
Summary: I have used it 3 months now. The NOISE drives me nuts. I liked my last Sharp Microwave so I felt comfortable getting a replacement. The START Switch broke on the old one. This new one, the R1880LS microwave / convection cost a lot of $$$. But it has a lot of nice features. However just using the MICROWAVE, IT IS THE NOISE that gets to you. The Magnetron is noise, The heat fan is noise. The cooling fan is noise.
