Has anyone else built these? Personally I think Bumble Bee was the best build and feels very sturdy....Soundwave is good as well, just not a sturdy. Optimus, on the other hand, was a good build but the quality is far less than the other 2. His leg/hip joints are not good...they slip out of place if your trying to pose. Also, I like how the gave BB And SW opposable fingers, not O. Over all I'm happy, just wish that Optimus didnt feel like it was going to fall apart when I pick it up. ...
