these are irritating because kids are no longer riding them but are still leaving them all over the sidewalks to be tripped over.

I believe some people in big cities actually use these things, so for that they can be of good use. However I do the pricing and signing(or if you will the advertizing) for a company, so I see what comes in, what the trends are and what fades. The Razor Scooters were a trend a couple of years ago and they died out fast we had too many left over.
