Query: Unreliable toy

My dad bought two of these tiggers for my two little ones for their birthdays and they tiggers kept falling over no matter what surface of floor they were on. We ended up taking one of them back and we thought it was a manufactuer defect but it was the toy in general. The second tigger we bought did the same thing. Every now and then it would work but less often that it should. Very upsetting to the children. This toy is truly a waste of money. We love tigger but I would not purchase this one if you truly want to be satisfied!
