This replaces a GE 1/2 hp unit that just stopped working one day.  I was hoping for something quieter with at least the same power, but what I got was much of the same.  This isn't necessarily bad, it does it's job just fine, but I was hoping for something quieter.  Over the counter, the Moen was about $20 more than it's competitors, but it had a better warranty, so maybe it evens out.  Overall, this is a fine disposal unit, but nothing special.  Install was very easy; easier if you have an outlet to plug it in.
