I bought a Berkley E-Motion not long ago from Acadamey and when i finally got to fish it I noticed there was a rattling coming from what seemed like inside the blank, under the first eye. I don't believe I can return it because it's been a couple of weeks. I was just wondering if it's something I should be worried about and what's causing it. Any ideas?

Try to return it, these stores will usually take them back still as long as it doesn't look used or damaged. 

Academy seems to have good customer service. I would attempt a return as well.

Thanks, guys. Gonna try to take it back today.

Well, took it back and got a 6'6" MF Daiwa AirD X, as well as some reel oil and cleaning swabs (cleaned my first two reels without cheating and using YouTube or Google), and some Power Pro Maxcuatro that was on sale for $12. Haven't gotten to fish with the rod yet, but it seems pretty nice. Wish I could've found at least a 7', but it happens.
