Johan, people have this thing called a budget. RUP is cheaper, therefore, a better option for some.Nononono don't buy your son a Razor scooter. This is not a good scooter at all. I don't even understand how some people would recommend an Ultra Pro over a complete Blunt.
It has metal cores
Flex fender brake
stronger deck
Stronger bars
more solid.
I can not come up with one part on the Razor which is better than any part on the Blunt Complete. Trust me. The Blunt complete would be the right for your son
Madd Gear scooters are way to heavy. And the Ultra pro isn't a nice ride. Blunt is the perfect scooter for him.
