Title: Lots of fun, but unreliable
Review: It's fun--great to play with on hardwood or tile floor. I don't think it works on low pile carpet as it claims, but it provides good indoor fun and exercise with minimal danger to people, walls and furniture. UPDATE--I liked it so much that I bought one for my nieces and nephews, but theirs never worked. I don't think they ever bothered to attempt to return it.
Is the review positive or negative?
