This review is from: Science Museum - Robot Duck (Toy)
Like other reviewers, I found this product to be fundamentally flawed: the robot is too heavy for the promised 'walk', and also the instructions lead you to (unintentionally) wire up the duck to walk backwards! There is a passage in the instructions which suggests solutions if the duck walks backwards: we tried them all. Reverse polarity, reverse batteries, even mixing red and black wires - but nothing solved the problem.
My son - who loves robots - enjoyed putting it together but when it failed to walk he lost interest. The single sheet of 'educational' insight was missed entirely - it would have been better incorporated with the instructions so users can learn as they build.
There are other robots that represent much better value than this.
