Heavy construction seems very sturdy, I don't have an opinion on its use yet. I got it for a 6-year-old child, it is at the lowest height and it is fine. The handlebar goes up quite high, so if it lasts, it will easily cover a larger age range. The downside is that it has a smaller base inside the box, probably for smaller children, but the one that is already on the scooter does not unscrew even with a compressor, so we cannot change it. Also, it came with 2 keys for the screws that are the same and only serve to screw the handlebar onto the scooter, but it has many screws that need tightening during use and you have to look for keys. This is a bit of a concern because you can find them easily. If I manage to change the base to make it more user-friendly, it will improve a lot. Finally, it says it is for 3-year-olds, but it is not suitable for such small children, it is very heavy, about 5.5 kilograms.

While at first it seemed sturdy and solidly built, soon the front wheel did not turn well and the worst part is that before even a year passed, the plastic base on which the child stood while scooting broke...almost causing injury. (Supposedly it can hold up to 50 kilograms...the child weighs 35.)
