I purchased this cooktop and decided to go with this option because all of my other Samsung appliances have Wi-Fi connectivity. When it was time to install, not only did the was it too large for my cutout (even though my old cooktop was also 30 inches) but the module did not fit because of the backsplash. Turns out the installer says this happens 90% of the time and they had to remove the module. Now i ended up paying for a premium product to get a feature that i now can't even use. No mention of extra space needed for the module was ever mentioned.
