Product review (5 stars): Perfect for my needs.
I just spent over $300 to purchase a new rubbish disposal, not including the cost of the plumber to install it. The new product was so concerned with keeping the noise down that it wouldn't drain without my pushing down the rubber baffle to allow it to drain. The InSinkErator RSB-OOO works perfectly, allowing the sink contents to drain without assistance and the sound is still baffled.
