Product doesn’t sit flat because one of the brackets attached to the cooktop sticks out farther than the rest. Frigidaire sent a repair man who as soon as he walked in said he couldn’t do anything about it. He sent pics to the company and says they would contact me. I’ve never heard from anyone. I love the product. Just sucks to have a brand new kitchen and a wonky cooktop that everyone can see us not sitting flush on the counter. Our contractor said the bracket is like permanently attached to the cooktop. For as much as we paid it should be perfect. Very disappointed in the customer service.
