Does anyone have this stroller? I am looking for the most lightweight stroller possible. I live in Israel and need a stroller to walk to gan, and around the neighborhood but I live on the second floor with no elevator so it needs to be light enough that I can bounce it up the stairs or hold it in one hand and my baby in the other for when we take buses. Right now I have a $10 stroller from Wal-mart and the wheels are just so bad (keep getting stuck) and I'm getting fed up! Thanks!!!!
