We replace a long owned (15 years?, maybe more) Insinkerator and did not consider buying another brand.Because our kitchen is open to our living/dining room It is also important to us that it be quiet, which I am delighted to say it is.
We had it installed without any issues what so every -- though in fairness it was a pretty easy swap out of the former one. It has been in place a month and I couldn't be more pleased with it.
