This is our third insinkeraior. I love it but it wears out very fast.I love it but every time this happens a plumber charges at least$150.00 to reinstall a new one.I am an interior designer so I have suggested this to several clients but I do tell them if they get one that the life use of it is about 3 to 7 years. I would hope that you will try to work on increasing the length of the life of this product.
