It's only been about a month since I installed this cook-top. So far it has completely lived up to our expectations. We particularly like the range of heat options. The largest burner at 15000 BTU can heat a pot of water in no time while the smallest when turned to its lowest setting is a true simmer burner. Installation was a bit of a challenge as the cook-top we replaced, while the same width on top, was recessed more so that the cutout needed to be enlarged. At the same time the depth of this unit is greater than the old one which means it impinged on the sidewall of the cabinet next to it. So it took longer than expected but turned out great.
