Here's a technique I used while I was in Vietnam to tell for fakes. It is the simple process of feeling the racket with your fingers. Feel any parts with words like the MP100. If it is totally smooth, it is fake, if it is a bit bumpy, then it is real. The most part is feel the different parts in the racket. Like the MP100, feel where it goes off to different material from the red to the grey. If it is smooth, then it is fake and therefore painted on. If you feel a difference in the texture, then it is different. LMK if this works with your own rackets. A bit hard to explain, but once you get the hang of it, you'll find yourself in asian badminton stores trying to feel the authencity of rackets.
