Product review (5 stars): Perfect Fit
waste king 3101 ISE Adapter Kit, fit perfect.  But after all was said and done, I am not positive that I needed this adapter kit.  I think that the parts that came with the disposer would have been adequate to complete the installation.  Whatever.  The extra $10 is no biggie since the disposer was such a good deal and having all possible parts before tearing my only kitchen drain apart was great piece of mind.
