Title: False negatives
Review: The item seems sturdy enough, but it returns false negatives now. My daughter selects the correct dot and it says it isn't correct. The cards have not been used enough for me to believe that the dots have worn out so I believe the pen is no longer working properly. I'm quite disappointed.Great idea, poor execution.
