Although the time between purchase and installation was lengthy I am happy to report it was all worth it. This beautiful LG cooktop replaced a 20 year old cracked and failing cooktop and I could not be happier! The child lock keeps my kitties from turning on a burner with their paws (although I keep it covered so they don’t walk on it anyway.) The controls are easy to use and only having to touch the number selection for the level of heat is so much easier than sliding your finger around the numbers. The burners heat quickly and cool down faster than my previous cooktops. I am so pleased with this purchase! Now if I could just find the LG double wall oven I want to replace the current 20 yr old microwave/oven combo that is rusting away…
