I purchased the Max Burton 6000 Induction Cooktop because my gas range takes forever to boil water compared to my electric range. I did a side-by-side test, cooktop vs gas range. Identical pans, same amount of water at room temp. The two pots came to a boil within seconds of each other.The quality of the cooktop was fine. It just didn't do what I purchased it for so I returned it. Would have kept it if I'd needed a spare cooktop.
