Product review (4 stars): A well designed product, with a poor material choice for burners.
We've had this stove top for about two years, and are generally very happy with it.  The layout works very well for such a small surface area, 30".  You can use all of the burners when you need to.  The high power central burner is great, and really puts out the heat.

It is easy to clean, looks great, and there is one issue....

The burners are made with aluminum, and after two years of use the center burner has warped, and even bubbled. We noticed that the burner flame was uneven, and over the course of a year became more so.  Finally I could see why.

GE would not replace this for free, they charged $40, and said the actual cost was $120.  With the replacement burner, it works great again.  It seems like having flame coming out of an aluminum base is a poor material choice.
