I am planning to buy pogo styluses but my friend warned about fake pogo styluses. So I ordered on eBay a pair of these for comparison of the two models, ordered from separate sellers. When the performance was iffy on both units so i am doubtful that both units are fakes. So if you guys are using pogo styluses than tell me that how i will get to know about pogo styluses originality, and what should i do with two pogo styluses i purchased??
