I liked everything about this product. I could get it in white, it had cast iron grates, and looked easy to clean. The burners light immediately. However, when it was installed, it didn’t lay flat. My older GE cooktop was fine. This had An approximately 1/8” gap at 2 of the corners, so I returned it. The replacement cooktop had the same issue. Also, instructions say to remove screws on the sides to install the metal straps to hold it down. The screws were stripped and would not come out. Both of the cooktops had the same problem. I gave up and just kept the 2nd cooktop.
