I bought this recently so I haven't had it long. It was easy to install. The price wasn't bad. It seems quieter than the kenmore we've had for 20 years. Yet still seems to function just as well. Please note we don't put much into it except some small food particles. So I wouldn't know how well it works for those that put a lot of food waste into it. But for our means it seems fantastic. We bought the smaller powered one. And I run it every day for a few minutes to clean out any stuff inside. I only gave it 4 stars only because I haven't used it for but a couple of months. It has a one year warranty. There are others that have longer ones. I hope this one lasts a good while.
