I bought this Micro Scooter for my son (3) at Christmas. Due to his age, he has only used it when supervised; therefore, I know the scooter has not been misused. Nevertheless, after occasional use, the font axel, which the wheels are attached to, has snapped and rendered the Micro Scooter useless. The front wheel mechanism is made of plastic and based on my experience, appears to be very fragile (or perhaps the one I purchased had a defect!). Whatever the case, a poor quality product and a I'm left with an upset 3 yer old.
