Little did I think something so simple could be designed so poorly. We replaced our ISE Septic Assist disposer of 8 years (bad lower seal) with the updated model. The updated model came with the new Quiet baffle design. With an opening that is literally the size of 1/2" and baffles that don't fold easily, while it does keep things quieter, you will find yourself manually pushing down about 95% of the food scraps in your sink versus being able to rinse them down. Bring back the old design!!
