The Blanco composite sink has had several small chips over the past 1 1/2 years. There are only 2 people in our household and we're very careful with it. We had a lower end brand of composite sink prior to redoing our kitchen and it did not get any chips. When I contacted Blanco, their only response was that it was not under warranty. When I contacted them again and asked what could be causing the problem, they did not respond to my 2 inquiries.
