My 6 yr. old nephew purchased this from Walmart store today; PhD mother helped him with this while following all the instructions precisely. Did not work despite repeated attempts; We teased her about this, however she was vindicated when we read all the horrible reviews for this defective product. Unhappy child and frustrated parent. DO NOT purchase this product for yourself or as a gift. You will likely be disappointed. I called the manufacturers toll free number on the box and received voicemail. I am attempting to obtain a refund or I'll just take it back to Walmart.
