Hasbro Xtreme's loose tip

Hello, i just bought an odax o2 just to get the yellow xtreme but the rubber tip is kinda loose. It can be moved slightly in left/right/up/down directions (of course, it doesn't spin around :D).
Do i have to buy another odax? I hope it won't come off from the rest of the p.tip...
??
Nobody has experienced a similar situation with a Hasbro odax o2?
