Do 'touch panel' hobs work with wet/ greasy fingers?

[Whippet]

OK - based on the fantastic advice on my dishwasher thread yesterday today I'm looking at Induction Hobs.

I've always been a bit of a 'knob' person and I'm worried that these 'touch sensitive' control panels don't work very well if you have wet/greasy fingers?
True/false?

I've noticed that Neff do a magnetic knob as an extra on their upper ranges, which makes me wonder if there's a problem?

Mine don't seem to work if the surface is a bit wet - quick wipe with a tea towel & fine though. If I had a choice I'd go for knobs - quicker & don't get turned on by accident as easily.

My hob has a childlock to stop it getting turned on by mistake.

Obviously working out how to turn it on and off would mean reading the manual, so I don't actually know how easy it is

OK - quick report back - went to the cooker shop and looked at both, and DH feels the extra £50 for a magnetic knob is money well spent...

(Why does the last bit of that sentence sound like a candidate for quote of the week.? )
