Nice hob; works a treat. Just read the PDF instructions on the site first. It will drop straight into a 560mm wide x 490mm height worktop hole. Just be aware that there is a vertical vent to the right of the four operating knobs, which will require venting. I had to drill a few holes in the vertical panel to the right to allow enough venting room. Easy to use as the only touch button is the On/Off button, bottom right. Once it’s on, just use the knobs to fly it. Turning it off, leaves warning LEDs show which rings are still hot, solid light or warm, flashing light.
