There's nothing wrong with the way the stove cooks, but I HATE the location of the burner controls.  Why in front?  Also, what good is the sync burners control when there's no heat coming from the middle of them.  Geez, I could easily control the two burners without the sync burner control.  I really miss my "bridge" from my last 
GE stovetop where I could sear large cuts of meat in my very large rectangular pan.  The sync control is absolutely useless.  Last but not least, I do not need 5 burners.  I'm a big cook, but 4 burners are quite sufficient.  I own a double oven, a microwave, a slow cooker, so it's rare for me to even need 3 burners.  It's fairly easy to clean but would be a lot easier if the controls were on the side as on your previous models. I just don't understand why you would try to fix something that "ain't broke."  Overall, I'm very dissatisfied with this model cooktop.
