The gas hob in the house we've moved to doesn't have auto-ignition so just bought SWMBO a piezoelectric gas lighter.
It sparks fine but no way can we get it to actually light the bloody gas.
Doesn't matter how high or low the gas is turned, how near or far the lighter is, you click away until you're blue in the face and all you get is the smell of unlit gas.
Are they really this crap?! Never had any problems lighting the same gas with a match!
