I previously had a 10 year old insinkerator that gave out. The home warranty company wanted to replace with a waste king product that was not acceptable match to the stainless steel flange that I had. I called the customer service at Insinkerator and asked them for a comparable disposal in their line. I ended up getting the top of the line disposal and it is very quiet and superior than the one that we had from 10 years ago. It fit on my previous stainless steel flange that matches my Franke sink. Also the rubber part can now come out and be easily cleaned. I great upgrade to keep things cleaner.
