Micro scooter - bullet or sprite any good?

[TaraQ]

My daughter has hada mini micro for several years and obviously is a speed demon like all micro scooter kids! It is her 5th bday in a couple of weeks and she is obsessed with getting a 2 wheeled scooter. I want one for her that she can go fast on - many 2 wheeled ones I see don't look like they go very fast. Has anyone got the micro scooter bullet or sprite models? Are they any good? Do they go fast? Would they be suitable for a 5 year old? x
