The easiest way is to tell if it's a fake is to look at the price. The fake ones are selling forunder $100.00, as low as $55.00. If you order one, it will be shipped from China. PLEASE....buy from a reputable dealer! Those great deals aren't so great when you see how much of a piece of junk the knockoffs are, and good luck trying to get your money back.
