This hover board was packaged very well, I can tell it's made with good quality, and the instructions are very clear and easy to understand and go by. However, my son's hoverboard is small, because he is six years old and he can't ride it with his feet yet, but he can drive his sister's big hover board with the go kart attachment. This is the second go kart attachment for his hoverboard I have bought, assembled and tried to fit on his hover board, but has not fit. The last one I bought said fits “most” hoverboards from so many inches to so many inches, which was within the size of my son‘s hover board. This hover board is made with better quality, better instructions, and packed much better, but says fit “all” hover boards from this many inches to this many inches (whatever it says, is what I went by and compared to what my son has). Which is within my son‘s hover board size. So they lie about the size, but it is great quality. If your hover board is without a doubt in between the range of the size, go for it! I was so excited he was getting one with a flag. Disappointed. Will be returning, and trying again. This time, I'm going to get a measuring tape and measure in between the feet size, because I'm now sure these companies typically use the wheel to wheel size.
