After having this unit for over a year before it was installed waiting for a plumber, I decided to install the unit myself. It took me less then 1 hour to install and it is working just wonderful. We have been able to cut back considerably on our waste going out to the curb. My wife is so conscientious about what to put down the unit whereas I have tried quite a few different items without any problems at all. These include chicken bones,tea bags, leftover vegetables & table scraps. The only items we are unsure about trying are lettuce and celery as my wife is afraid that they might clog up the unit and not go through as efficiently as some of the other items.
