I've never liked reading testimonials, because you never put in a bad one. I was a little skeptical after reading them but also very excited. I know now what they are talking about and would recommend this class to anybody who wants to learn concrete countertops. I believe this is a basic first step to countertops. You have to know how they work before you can design. Without proper installation and preparation the best looking design might not work. I think Jeff is a first class person, who treats everybody well and knows what he is talking about. CCI is well run establishment.
