Save Ben 10 Alien Force 6" DNA Alien Heroes Brainstorm

I bought this for my son on sale since he loves Ben 10. It says it come with batteries however, it didn't work and requires watch batteries which was fine. The top of the brain snaps off easily which is a disappointment, especially when it's the first day. It does snap back on easily but it just snaps right back off a few minutes later. My son still enjoys playing with it but I probably would have picked a different toy if I could go back and redo it.Get more detail about Ben 10 Alien Force 6" DNA Alien Heroes Brainstorm.
