Razor spark scooter

If you have a razor spark scooter they are about £60 now but are they worth it for what they are? razor sparks in general are good scooters but the problem is that their spark cartridges last for about a month and then you have to buy a new one for about £7 at the lowest so if you have a razor spark scooter then you are better off take the black parts at the rear wheel off then you can take the spark cartridge out and then you just have a normal razor. The really good thing is that they have brilliant suspension so you can bunny-hop well and hang 5 pretty good if you are experienced enough.
