Chuck's Reviews Transformers Studio Series War For Cybertron Bumblebee
 

While given the first numerical designation, Bumblebee is actually the third figure released from the Gamer Edition subline. Of the three figures we've looked at thus far, I would say that Bumblebee is the hardest to transform, but the resulting vehicle mode is solid, smooth, and very small. While I'm happy with the included weapons, I'm disappointed that there's no place to store the arm while using one of the included blaster attachments.
Overall, if you don't enjoy complex transformations that can be fiddly, you might want to wait for a sale before buying Bumblebee.
