Was in the market for new cooktop and found my fav brand BOSCH makes them! Love it that I can cook 4 dishes  and keep 1 at simmer simultaneously, the sleek and clean look, the BTU power, especially the center one for some stir-fries! The knobs are pretty sturdy so hopefully it will not break like previous cooktop. One minor improvement wish is a lock for the knobs when cleaning. I believe the cooking time is definitely LESS than all previous cooktop I had in cooking delicious and healthy meals for myself and family! Very happy that I made this investment with things above-described while saving gas, time and money!
