This review is based on my comparison of the Waste King Garbage Disposer SS8000 over the Insinkerator ISE Model 777.
There is a chart that compares all of the waste king models to ISE models at waveplumbing.com. After my disposer was installed I noticed that it is much quieter than my old ISE. The higher RPM and longer warranty helped me make my decision to select Waste King over ISE.
I'd much rather have a lifetime warranty with Waste King than a 7 year warranty with ISE. And it makes sense to have the extra motor speed for the same price. Waste King at 2800 RPM over 1725 RPM with Insinkerator.
