What reviewers say

Both reviewers admired the transformation and character design. Engadget criticised inconsistent voice recognition and mediocre sound. GeekDad praised stable movement and custom programming, but wanted a cassette accessory. Both tested before retail release; GeekDad used beta software and could not test the promised Megatron interaction.
