Product review (3 stars): Performs as expected
When my 13 year old Jenn-Air downdraft cooktop quit working I researched other brands and decided on the GE because the new Jenn-Air has become quite expensive and there are not a lot of these type of cooktops on the market to choose from.
Pros: The GE performs very similar to my old model, as far as the time it takes to heat and maintaining the heat, so that was as expected.
Cons: The numbers on this model are difficult to see and I have to turn the kitchen lights on to see the settings. Thought it was just me, however several others have had the same comment.
In order for the surface to look clean with no streaking or smudges, then  Cerama Bryte  cooktop cleaner has to be used every time the cooktop is used. Just wiping it down with a clean dishcloth is not enough.
The installation went smoothly until we tried to connect the venting system, then we had to have a custom piece made as the GE is very different from the Jenn-Air venting system.
