I know this is an old thread, but I found it to answer a question that has been bothering me about gifting clubs to mobile users.
I recently (about a month ago) gifted a set of Taylormade's to a club member who had been using starter clubs. I tried to PM him about the clubs but for some reason it never got sent. I posted on his wall about the clubs and left it there up until just recently.
He is still using his starter set, and from what I can tell, has no idea about the gifted clubs. So my question is since I think he plays mobile, is there some sort of barrier with gifting mobile players? I see no other reason why he wouldn't use a more superior club.
