My daughter has this unicycle to get 9th birthday (driving beginner). At first I was a bit skeptical because the saddle is constantly rotated. After my husband has the saddle or the designated screw neatly pulled "tight", but it happens rarely, why only 4 stars. My daughter has become accustomed to, it reduces their driving pleasure not absolute. The unicycle makes me a strong impression, as it has already experienced some crashes, only the saddle is scraped off the front and back. For the price is right, the power ratio. Conclusion: we would buy this unicycle immediately.
