My daughter had her previous Razor scooter for about 5 years, and it worked great the entire time. When it became apparent that it was finally too small, we bought her this new one.  It was purchased in September of last year and ridden occasionally. Last week, she was riding it at the park, and pieces began coming off. The cotter pin, the bolt thing that goes through it, the spring... We had to go on a major hunt to locate all the missing pieces. Fortunately my husband was able to repair it - however, for the retail cost of these scooters, I find it inexcusable that they can fall apart so easily!
