I replaced an old Insinkerator (was in the house we bought 12 years ago) with the new Evolution Essential XTR and the first thing I noticed was the incredible difference in the amount of noise. The new disposal is so quiet I thought I had done something wrong, but no, this thing is so quiet you would think it is not even on. Very impressive! The power is exceptional as it grinds up everything so quick, its over before you know. Best disposal I've used anywhere.
