Sharp R-21LCFS 1000W Commercial Microwave Oven with Dial Timer, 120V - Medium Duty Silver (Updated R-21LCF Model) - Perfect for Restaurants, Cafes, and Food Service Businesses

After our previous two microwaves had their plates break or chip, and one of them started randomly burning food, I decided to see if there was anything out there that would be more reliable. We ultimately settled on this one, because even though it's more expensive than even the fancy consumer microwaves it has three important advantages that none (or very few) of them have:1) It is built to last. Everything on this microwave is purposefully simple and apparently designed to minimize the possibility of breakage. Instead of a plate that will get dragged out with the food and shatter on the floor, it has a glass floor that's fixed onto the body of the microwave. Instead of a push-button control panel whose buttons will inevitably crack or get desensitized, you have an "infinite rotation" wheel that is solidly attached; and because it's not calibrated physically it won't get out of alignment. Instead of a clock that you will continually have to reset, it has ... no clock. The interior is metal all around and all surfaces are easy to clean and seem resistant to scratching.2) You can intuitively and freely modify cook time while the food is heating. Just spin the wheel, and it does exactly what you'd expect. I can't understand why almost no digital microwave will let you do this, but now that it's easy I do it all the time.3) Instead of a carousel it has a different kind of heating mechanism that ensures even heating without actually moving the food. This means you can heat larger or odd-shaped dishes without hotspots and without knocking your plate out of alignment. I was surprised at how well this works in practice -- food consistently requires less stirring and has less temperature variation after heating than with any other microwave I've ever owned or used. Naturally you should still be cautious about checking your food before shoveling it in your mouth or feeding it to a small child, but it's nice not to have so many frozen-in-the-middle burritos or ice-cube-like tofu chunks in your leftover chinese food.If you'd like to use variable temperatures or auto-cook, or presets for popcorn, or have another clock or timer, or have something that's also a convection oven, or do anything other than heating food or food-like stuff in an intuitive and foolproof way, look elsewhere. If you are willing to pay more for a microwave that does one thing and does it better than you'd expect, this is the one.
