This thing is quiet.  In fact, I thought i had overloaded it and it was just bogging down, but it chewed right through everything i put in it.   It comes with the power cord already attached so I didn't have to pay 10-15 bucks extra like I would have with a few other brands.   So far I would HIGHLY recommend this disposer to anyone looking for a great item at a very fair price.   

Pros: Quiet, Affordable, comes with cord attached
Cons: none--I love it
