Mine went back yesterday - I thought it was me being feeble because I just could not get a good result - the paper kept sticking and the holes were often in the wrong place, plus the wires kept coming out oval instead of round.  I rang on Monday afternoon and it was picked up Tuesday afternoon, so very good service .  I have asked for a refund, as I don't think I would get £60 worth of use out of it even if I mastered it properly.
