If you bought 496 new, I'd return it. Personally, I hate pretty much everything about the Manfrotto ball heads. Their handling sucks, their plate sucks, they don't have a usable L-bracket and their stability is questionable.
If you're going inexpensive, the entry Sirui or Sunwayfoto ball heads are very nice. Generally I think the Sunwayfoto heads are better made. I got an XB-44 (which is their premium head that competes with the RRS BH-40) to review, and I like it better than my BH-40.
But seriously - save up a few more bucks and get a decent Arca-Swiss-based head. You won't regret it.
