The package with the "fixed" head can be identified by having a rubberband that holds the head in place during shipping. On the case of Brainstorms that I received, the ones with the fix can be identified by the small code on the back of the box (42791) which is different than the code on the unfixed version (42551). These codes may vary and may possibly not be the codes that identify the fix. Please share your examples with us if you find something that contradicts this information.
To clarify some earlier confusion from our Facebook page and in our discussion topic about this matter, the rubberband has nothing to do with the actual fix other than it can be used to identify which ones have the fix versus ones that don't.
Here are some images showing the differences between the two releases to help you identify the different versions.


For those who still have the initial release, the video below shows you how to fix it yourself.
If you're still on the fence about picking up Generations Brainstorm, make sure you check out Seibertron.com's massive gallery of this figure. Also, if you come across this toy at a retail store, make sure you share your sighting it in our Sightings section or on our Sightings forum.
