This thing works great with my stainless steel pans. Water boils in a few minutes. Came intact and ready to install. You do the wiring, it just sits on top of your counter.Installation was easy, but I did have to cut a few inches out of my counter top (it replaced a 30 inch GE from 1988); inside dementions are 29.5 inches by 19.25 inches, then there is a 5/8 inch lip around the top. Wireing was easy, it has 3 wires (hot, neutral, ground). No wiring instructions included, but it does require a 220V which is what most cooktops need anyway.Once on, it's pretty quiet. HOWEVER, one of the burners made a horrible noise when teh fan was on, I looked underneath and saw a wire had shifted during transit and was hanging in the way of the cooling fan. I used a butter knife to bend the wire away from the fan and now there are no noise issues with any of the burners.
