Thanks Mick, I daresay it's user error on my part with regards the DE. I do use the CT more though, so I'm more practised with that than the DE. The mach 3 lives in the wardrobe these days and is only dragged out, much against my wishes, on haircut days when the wife refuses to shave the back of the neck with anything else. She'll have to break from that once all the blades are used up though. I'm throwing it away after that.
