Bought this over the weekend to replace our old unit that stopped working. Very easy to install. From start to finish, less than 30 mins! Seems to work fine. It is a very quiet unit, with the only exception that it makes a "grinding" noise when you turn it on. It's no big deal for us since that last a fraction of a second. The unit that we replaced was the 1/2 HP GE unit. It was very loud and vibrates a lot even with little food waste in it. My suggestion is that you pay the $30 or so difference to get this unit. You'll be a lot happier!!!!
