So far this Gas hob is working absolutely fine however, one word of caution is to wipe any spillages away very carefully as the stainless steel top will scratch if using a firm wipe / scouring pad.
Also, I used AO to deliver and install the gas hob which they did a great job in doing and were very thorough in installing and testing. I did have to chase to get my certificate though as it did not arrive promptly.
