Smeg hob

First hob that was delivered had a long scratch, looked like a manufacturing fault. But AOL replaced it with no fuss whatsoever and the next day. The hob looks great, but I'm reserving judgement about how it functions. So far I'm not overly impressed: the gas is a little noisy compared to my last hob, and there seems to be less controllability in terms of heat/temperature/flame. However, it may just be that it is new and something I just need to get used to.
