Summary: I purchased this gas cooktop in Oct 2012. In less than 8 months the ignition stopped working completely. After working with the factory and having me replace all the wiring they finally agreed to replace the entire unit. In less than a year since the replacement the ignition on one of the burners failed again. I replaced the battery and it still won't work. I am now replacing the entire unit with a electric start (plug in) ignition in a different brand.
