Our old cooktop was definitively past its sell by date so we decided to upgrade and The Good Guys were my first and only choice to shop for a new one. Ian the sales guy was very helpful in showing us all the ones that were compatible with our granite surface and we chose the Smeg 60cm Classic as my wife and I really love their style. Ian recommended a great plumber to install it. The Black Ant Project were really quick and efficient in fitting the cooktop. A little granite had to be sliced away but this proved no problem and was done with little noise and no mess at the end.. Great job all round.
