I bought this for my wife for Christmas and it made no mention of a foil shaver attachment that is sold extra for under the arm shaving. Well, the day after Christmas my wife was excited to try the new shaver and shaved in the shower using shaving cream. She shaved her legs without issue but then when she shaved under her arms, it shaved the top layer of her skin leaving it red and bleeding a bit. I took a picture yesterday which was 4 days after she had shaved to send to Skull Shaver. It was much worse after the shave. After googling this we discovered that Skull Shaver sells separately a $ 19.99 Foil Shaver Attachment that is designed for "under the arms and behind the knees". Of course this was little too late and cost us an additional shipping fee when we ordered it immediately. In the shaver, it included a face massager. I would recommend that if it is a price point decision, they should include the foil shaver attachment instead of the face massager or include all three as a standard kit to avoid future under arm pain with their new clients. I use the full Shaver for my head and that is why I bought it for my wife, because I love mine.
