I called them and they're apparently sending me vouchers. She was very sorry, assured me that it was a manufacturing fault and it is being dealt with. She didn't say how much the vouchers would be for, but I asked whether they'd cover the cost for replacements and she said yes. I don't think I was as bad as some though, just had a raised red welt which was a bit sore and I figured it must be a dodgy razor. Luckily, I had bought the black invisible one too which isn't listed so started using that and it cleared up immediately. I did ask whether the faulty ones had been removed from shelves and she said they're trying but there may be some left... So I think I'll be sticking the invisible one for the foreseeable. Shame, as it doesn't smell as nice as Shower or Powder Fresh.
