Anyone with the quinny zapp extra fold stroller I had a couple questions that I can't find the answers to. I'm so afraid to order tell I know the answers that's a lot of money to spend lol.

Questions -

1) is it able to be used for infants as is (no car seat)

2) dose it go over rocks, grass, dirt and things like that good?

3) how big is it folded up (measurements would be awesome)?

4) is it tale enough for most people? The handle bars seemed kind of short
