This unit replaced a six year old badger 1 which always bugged us because it was so loud. So selection of a quieter unit was desired when replacing. The badger was still working, but we replaced it at the same time as a new faucet was installed. We are very pleased as it is much quieter and the install was simple since it used the same old sink hookup which saved having to re putty under the lip. Just lifted it into position and turned to clamp onto the old. You will need to adjust the plumbing hookup though, as this unit is wider and a touch longer. Overall a great upgrade, very quiet, grinds well, and even looks better than the old unit! Enjoy!
