I ordered this bag (pink and black) because it was low-priced, the right size for me, and I thought it was cute.  Indeed, it was all of those things.  It had plenty of room for a week long trip and rolls pretty well.  The biggest problem is the tipping over.  I read other reviews before purchase, and they were correct.  While this isn't a huge deal if you are just trying to roll the bag by itself [carefully, that is], trying to put a laptop bag on top of the handle (like many luggage sets are made for) is just not practical.  Why the company did not put some "feet" on it like other luggage I do not know. For a casual once in a while trip, this bag will suffice.  For a frequent traveler, I wouldn't recommend.

Pros:

Very cute
Unique- so easy to find if you check your luggage
Enough space for a week long trip
Durable, so far for me
Rolls easily

Cons:

Tips over (no feet)
Dimensions, while carry on size, are a little large compared to some
Not practical for balancing an additional bag on
