Just so everyone knows, the Optimus prime voice changer has two versions: one features Peter Cullen's voice and other features a knock-off voice. The packaging is almost identical except that when looking at the packages, on the left side, the Peter Cullen one has a yellow sign that says "TRY ME! Feturing the REAL Movie Voice!" and the knock-off voice one says "TRY ME! Press buttons for Battle Phrases!"

Target had the knock-off, while Toys R Us had BOTH versions side-by-side!
So keep your eyes peeled folks to avoid getting the Hasbro Janitor voiced version of the helmet!
