Having had a high end competitor model for almost 40 years it was finally time to replace it. Looking for at least a comparable and one of the batch feed style we found the Evolution cover control Plus model by Insinkerator. Operation is similar to past model owned. finding a batch feed model ws not the easiest of tasks. Most models on the Market seem to be of the throw away variety. The new Insikerator model with its eas of insulation looks to be comparable replacement and on its way to being a 40 year replacement. Very satisfied with this purchase. Would recommend this simple to use but very safe model !
