I love my quinny zapp and I am waiting for them to invent a double zapp!
Ok, there's no seating positions and not much room for hanging your shopping over the handles but if you have a predisposition for an aching back or are not very strong then this is the buggy for you.
Folding and unfolding is not very hard, I did practice indoors a few times before I took it out , and I have even put it in my bike basket strapped on with a bungee for transporting it somewhere.
I look after a baby who is one year old and weighs 30lb!! He's very heavy and I used to push him in a mothercare standard umbrella buggy until every day my lower back would ache and be quite uncomfortable, so I splashed out on a quinny zapp and I would not have anything else now. I can push it with just my little finger and I wish all pram manufacturers would design a lightweight and very fashionable hi tech pram for people to push their tots around in.
You can buy a net shopping bag off ebay for a few pounds to put your essentials in.
