I purchased this bag because I wanted something slightly larger than the mosey hatchback for weekends.  Overall it's a great bag: it looks very cute and the convertible straps are incredibly useful.

That said, there are a few improvements that could be made.  First of all, because of the way the bag is constructed the main compartment is really only about 2/3 of the height of the bag (you can see this in the side view of the product).  This is probably very efficient from a manufacturing perspective but if you're carrying a bag that occupies a certain volume it would be nice to be able to actually use that space.  In addition, the curve of the zipper makes it a little difficult to close with one hand and on occasion the zippers can work themselves open (I've added a small s-biner to keep this from happening).  The snaps of the side compartments can also be fiddly to open and close.

So, a couple of flaws but in general I'm very happy with it.
