I purchased Western Premium's WP36IDDA(the only one they make) Induction cook top with 3 speed down…read moredraft. I have had the cook top for about three months. I have cooked with both electric and gas before. I LOVE INDUCTION!!! It heats up faster (you save on electricity too) and cools down faster than either electric or gas. You have heard if you watch water boil, it will take forever? Well, you can watch this cook top boil water and within a minute the water will be start to bubble. Depending how much water you are boiling, but it's the fastest for either wok cooking or pasta water. I cannot turn up the unit to high with my wok because it will get too hot ( I never thought that was possible??), so hot, the oil will smoke to the point of causing so much smoke I start to choke. I would guess if I left it on high, my wok would melt!!! And no, the downdraft cannot keep up with that much smoke, not even an overhead fan would work. The downdraft works as well as can be expected for a downdraft. Now once I turn the heat down, within seconds, it stops, almost like putting "on the brakes", even faster than gas (because with gas, the flame heats up the grate that the pot sits on and so there is more conducted heat to dissipate); so as a chef, you have complete control. Not having gas, your kitchen stays much cleaner and no CO2 to worry about. And yes, this induction cook top will work with a wok, lifting to toss food and back again, it takes about a minute for the burner to turn off with a pot off of it, so woks work fine. You cannot slide a wok on it (might scratch the glass), but you will quickly adjust to lifting it up first, then toss. The fifth burner is a warmer that keeps food at around 125 degrees, perfect for sauces. All of my questions and concerns were answered by Jennifer Cook; so you can talk to a real person anytime you have a question. Everything about this cook top is heavy duty and should last past it's two year warranty. At this time, there is not an extended warranty available. My only cons are both on the grate of the downdraft: 1. it moves a little and when cleaning it knocks against the glass; I just used a rubber gasket to stop that. 2. the grate has big holes in it and food or anything can drop down into the filter area (the filter will catch anything, but), I put a fiber filter on top of the grate so nothing can drop down and it does not reduce the downdraft. So time will tell if this cook top will stay at 5 stars, but I would be surprised if I have any problems in the next ten years and I cook everyday!!!
