Bought it to replace a leaky 12 year old model that came with my house.  Install was average for a DIY person.  I used the outlet plumbing from my old disposal and everything hooked up easy.  The most unique thing I noticed was how quiet this model is!  When running it the whole house no longer knows I'm at the kitchen sink!  Plenty of power!  It's also significantly lighter than the old one as well. Very pleased so far.
