This bag is GREAT.  It rolls like a dream, is well made, and fits the height/width requirements for carry-on.  I would prefer that the handle locked in the second position (in between being all the way down and all the way up.) But it stays in that position for the most part when needed (I would just prefer locked.)  Also, in one of the smaller airlines I did need to make sure that I didn't have the extender zipper extended.  I had a messenger bag that I threw into the suitcase on the return trip and I extended the Spinner to fit it.  With the bag extended it wouldn't fit into the overhead compartment.  I removed the messenger bag, zipped down the extender and, viola, it slid into overhead.

I like the purple, it stands out.  I'm crazy about the bag.  I fit a good amount of clothes for a 6/7 day stay.  I slid an iPad into the front pocket and was set for my trip.  I also bought the 3-piece packing cube set (in eggplant) and these were fabulous!
