From customer email: "I have had some nasty cuts whilst using the following recommended safety precautions for a blade razor, e.g. making sure I tighten it enough and only let it 'glide' over my skin. It seems that the 'protective' case surrounding the product for some reason or another, does not seem to be sturdy enough in the one I have been using... The razors seem flimsy and flop about inside the product."
