30 years ago our disposal broke at our beach house and the plumber told my mother that a new one would not hold up in the salt air environment. after three decades of scraping plates and clogging the sink, my son and I bought this one and installed it without asking. This one was more expensive but I didn't want to deal with wiring a switch because the plug outlet was there. First time installing and we did it on under 2 hours. 7 year warranty and my mother, wife and entire family is delighted.
