We are about to get this Neff 5 ring induction hob - T48FD23X2 www.appliancesdirect.co.uk/p/t48fd23x2/neff-t48fd23x2-4-induction-hob-hob. But I am worried it won't be as good as my Hotpoint one... On my 4 ring Hotpoint induction hob, the buttons are quick to respond. You can hold your finger on the button and the numbers go up or down quite quickly. And when you have all 4 rings on high power mode, it does the job with no noise or fuss. But when I had a go on my friend's Neff induction hob (admittedly a 4 ring not the same model as the one we have on order) the buttons seemed very slow to respond - cycles through the numbers slowly, and when more than 2 rings are on, it makes a loud clicking on and off noise, and loud humming. Is this normal Neff induction stuff? should I be worried? any help welcome, thanks so much.
