          It’s my dream come true!
          As my joy of cooking grew, I searched for a professional cook top with professional characteristics and lost faith. Then I installed a Bosch 6 burner with 2 high btu sear burners that reduce to a slow butter melt heat that allows me the freedom to boil water for pasta in minutes, sear in cast iron in seconds and simmer pudding without burning. The cleanup is simple as grates pop in the dishwasher and the sealed cooktop allows cleanup of spills or spatters in a simple wipe. I love it
            Love my gas cooktop
            [This review was collected as part of a promotion.] I hadn't used gas for over 30 years. I love the way my meals are turning out. I've received numerous compliments on the appearance of my cooktop in my space

              Rusty spots apprearing all over the surface
              We have been using the cooktop only for 3 days now. In the night we clean it with plain water and sponge. But we started noticing rusty spots all over the stainless steel surface of the cooktop.

                Knob setting for high flame…
                [This review was collected as part of a promotion.] Works great. Only been cooking on it for a month but it's a fine piece of metal. One simmer two super mega btu burner and three normal burners.Only downer...turn on the knobs to get the ignition to lite you turn counter clock wise..then clock wise to high. On the simmer and three normal burners there is no indent position for high but there is on the mega btu burners. Should be on all. Easy to go past high to off. But it is a minor annoyance. Over all I'd buy another.

                    Great Product
                    [This review was collected as part of a promotion.] Exactly as advertised. 2 high BTU burners and easy to adjust. great simmer too

                      Fabulous cooktop
                      [This review was collected as part of a promotion.] We are so thrilled with this cooktop. Full use of the space with the knobs on the front, burners work well, and we love the griddle pan that we bought to go along with it. So happy with this purchase!

                          Very disappointing
                          [This review was collected as part of a promotion.] We bought all new 800 series appliances. We are very happy with the dishwasher, fridge and ovens. But it takes an engineer to get the range top burners to light . You turn the knob and have to apply pressure for up to 10 seconds while the thing sparks to have any hope of getting the burners to light. The central one in front rarely works even with that. We had the authorized repair guy out and he seemed to think that was normal. It certainly wasn't normal with our old kitchenaid. So I guess we're just out 3 grand.

                            Would have given it a four or five
                            [This review was collected as part of a promotion.] but the large far right buner was defective when the cooktop arrived and it took about two weeks to get it repaired - otherwise I love it. Got a portable two-burner skillet for pancakes and it worked great! Easy to clean and maintain.
