... but with the Evolution essential, we can barely tell it is running! It costs a little more but knowing that there are no regrets everytime we hit the button, we are pleased with the decision to purchase again. Highly recommend. We bought the same unit in our last house, the decision this time was easy! Both houses on a septic system, love this product.

BTW, the new house had a thicker counter and we needed an extension for the button body that went through the sink and countertop. One phone call to the service department sent a free extension, received within 3 days. GREAT SERVICE, if it is ever needed.
