Do you happen to have a link to the pieces you got at BestBuy? I don't mind using my existing Aker mic, I just don't like having that huge transmitter in the helmet. My head is big enough as it is.
Not questioning you guys by any means, but what gives it away? I'm trying to be able to spot the bad ones so I don't have to ask questions like this. And I know the general rule is just stay away from ebay anyway, but this looked like a decent set.
