The money  I paid for these (like 25 bucks or so) was definetly worth it!!It takes a bit to get used to balancing yourself to be on one back wheel, but once you get it it's really cool. The quality seems pretty good. Not sure if I would recommend these for younger kids,you really need a good sense of balance. My 11 year old is a pro on them now but I would wait to get them for my 7 year old even though she has a good sense of balance. They have lasted almost a year with use as roller skate and regular shoe.
