Product review (3 stars): Designed in China ?
The knobs are plastic and very flimsy for a $1500 cooktop. Hard to install because the exhaust duct is rectangular and they force you to buy an adapter for round duct (even say so in the manual). With the adapter the whole rig is too long and almost touch the bottom of the cabinet and you'd have to cut the adapter to make it more manageable. Even so you can't use existing hard plastic elbows and would have to buy flexible aluminum duct because of the minimum clearance. It's really stupid and I can't think of a reason why GE would want to design something like that - unless they just want to annoy their customer. Or perhaps it's designed in China for Chinese duct since GE had sold their appliance operation to the Chinese.
