Just used the luggage on a holiday trip and it worked out perfectly.  We bought it for our 9-year old daughter to use as a carry-on when flying.  It fit all her clothes for our 4-day trip and it had plenty of room left over for her presents on our return trip home.  The luggage has a nice zipped compartment in the upper half of the clam-shell where you can also place shoes in a couple of elastic pouches.  The wheels rolled very smoothly and the handle can lock in 2 extended lengths so was fine for my 9-year old or myself when I needed to wheel around her luggage.  I like how the shell is quite thin making the luggage light and also more efficient space-wise to allow more stuff inside the bag.  However, being fairly thin, I wonder how long it will last.  As a carry-on it will work fine but wonder how well it will stand up to the abuses of checked luggage.  But for the price, I am not complaining.

One drawback is there is only one handle on the top of the luggage.  It would have been nice to have extra handles on one side and the bottom to be able to pull out the bag from a trunk or overhead bin if you have to put it in wheels out.  Otherwise, I would recommend it.
