A four-wheel segway

I know there are some people that are quite naive when it comes to buy the newly-fashion gadgets, but to actually buy a 4-wheel segway?

I can already imagine this call between two friends:

- "Guess what! It wasn't cheap but I got one of those wheely thingys that we see everywhere..."

- "Oh, you mean a segway!"

- "Yeah, that! It's a real beauty"

- "And have you managed to keep it balanced? I heard it can be really difficult to get used to the balance motion on the two-wheel drive"

- "Two-wheel??"
