My daughter got her scooter in January for her birthday, so we've had a good eight months with it. I thought it was only our scooter but another girl at my daughter school with the same scooter has the same problem.. The front wheel will get stuck.. Basically there is a pink plastic part that is just above the front wheel you most probably would see if you enlarge the image, what it does it dropped slightly so it would make the wheel stuck like a brake.. It's very sudden, like a stone has got stuck in the wheel arch. Luckily for me, my husband builds bikes and he was able to remove this part as its not really needed on the scooter it more for show.
That is the main thing they could have improved on it, and I know it wasn't only our scooter. The sticker on the handle post has totally gone now, could scooters alway live in the garage so are not out in all weathers which I found a little disappointing but it is generally a good scooter for the money.. The main foot sticker is still in very good condition considering my daughter goes to school on it every day.
My daughter is happy enough with it, as long as it has Hello Kitty on it, that kids for you :D
