Chuck's Reviews Transformers Rise of the Beasts Command and Convert Animatronic Optimus Pr
 

If you've ever wanted an Optimus Primal toy that responds to sound and auto converts, this toy is for you! Optimus Primal is beefy and chunky, the toy responds to sound, not voice commands, so anything from a whisper to a shout will trigger one of the over 100 commands. If you were looking for a bargain Robosen Transformer, you'll have to keep looking. At $125 I find the toy overpriced, especially since AA batteries are required so I recommend waiting on a sale that would bring the price down to the sub $100 range. Other than that, this is really fun and something a whole family can enjoy.
