This is my daughter's second pair of Heelys and well worth the money spent.  She has put a lot of use into the first pair and they held up beautifully. I have been amazed at how well the wheels themselves held up in the first pair we owned and it is part of the reason I didn't hesitate to buy another pair. I notice how often other children watch as my daughter skates around in her Heelys and I have had numerous parents ask me where to purchase a pair. I will say, using Heelys does take a fair amount of coordination and balance.  The concept seems easy, but actually using them takes a bit of practice.  For children who like to skate, I highly recommend.
