Query: Nice bag; good value; but may not be convenient enough for use

The bag looks nice and has lots of divisions and pockets. The included battery alone would cost as much as the whole package so it is a good value. Not that I need another battery immediately, but it is comfortable to know that I have a spare with me all the time.However, the bag tends to slide off my shoulder, especially when I have to bend over to attend to my other lugguage. I am thinking of acquiring another backpack type bag and a camera case.
