What can hang out in macbook pro retina 15 2015?

Question

macbook

Hello everyone, I became the owner of a MacBook, everything pleases, except for one.
When you turn the laptop in the open state from side to side in it, as if something is beating against the walls, they brought it to the store and changed it to a new one, and the new one has such a problem :(
Tell me who has a poppy of 2015, does everyone have such a problem? Or just me such a messed up series?

Answer 1

Found a thread on ifixit . Maybe it's bad glue on the battery and it's rattling.

Answer 2

Only you
