Input:
I got this for my son for his 9th birthday. He LOVES it! It is the perfect size for him and I like that it doesn't go too fast. Assembly was easy. I knew from reading reviews that it takes about 18 hours to fully charge. I made sure to assemble and charge the scooter before giving it to my son on his birthday. This way he was able to use it immediately. I can't imagine the torture it would have been for him if he had to wait. The enjoyment this scooter is giving my son is unbelievable.
