I wish to share my knowledge so other people can recognize them -
A) The first thing I noticed about the fake grips was they did not have the tacky feel in the soft red rubber part. There meant to be multi compound and the fakes were just the same compound.
B) The seller sent me an extra grip by mistake so I putt onto the club and all the colours started running off onto my hands.
C) The rubber is quite thin at the ends and the consistency thickness is visibly thinner at the end of the grip.
D) The fake grips are a shade lighter.
E) The main noticeable difference is the pattern is very, very slightly different.
I have included a couple of photos. Beware the fakes are very good and you can only tell by comparing them closely to the real thing. It was the lack of tacky feel that alerted me to have a closer look.

 

 

 

 

Lastly the thickness of the black bands are too wide on the fake and the c shape black crosses near the white band is too round on the fake below.
