We also have a Microwave which is quite old, but it's loud, it also has a "grill" function which nobody uses since there is something on the top which has to be cleaned because if you use grill, you will see smoke and smell fat. It also has no "digital" screen but those button thingies and you can spin them to set the remaining time. You can also adjust from 900 Watts to 100 Watts. We had it now for more than 20 years. You can unscrew it too.
I still have and use my old Proline Microwave from 1987 - works perfectly - the trick is to clean it after every use :-)

I was 8 years old when that thing was in the stores being sold. I didn't even know they had a fan on the top that's pretty cool.
