I gave this four instead of five because of the lack of a sunshade for baby. My baby doesn't mind wearing hats, so it's not a problem for us. He seems to be very comfortable and secure in this, and it's pretty comfortable for me to wear. His weight is balanced on my hips pretty well. I think it's a lot nicer than the other versions out there, as long as you don't need a sunshade. I like the detachable backpack it came with, too. I would definately buy it again, especially for the price. It is comparable or nicer than the ones stores sell for upwards of $100.
