I bought my quinny with 4 wheels online from the US about 2 years ago for my then 10mth old. I LOVED that I can steer easily with one hand if im carrying a bag. its quick to monouver, is narrow for isles, takes up little storage in the boot, is lite to lift and when we went to qld carrying it in its bag at the airport made it super easy. I cant wait till my 3mth old is big enough to go in it so I can leave my big pram for big days out.
I also bought from big w a little bag to attach to the back that can hold my keys a drink and a nappy which means i didnt need a nappy bag.
This pram is all about minimising what you take out with you. If thats what your after - this pram is for you!
Only downsides is not great for big shopping trips as there not a huge amount of storage (my version did come with a bag underneath the seat) which can hold at least one bag of food shopping and it doesn't lay back so better for kids that don't fall asleep at the drop of a hat!
