Well, the one found locally may be a Chinese copy, odd but true. I once bought a Moser head trimmer that I have seen professional barbers use and got it dirt cheap. A few days/weeks later it broke and I went to the guy. He admitted it was a low cost copy that looked just like an original and gave me a Kemei original that worked flawlessly.
