I purchased this for a cruise my son was going on and we needed something that could go in the over head bins. I will need it myself for a trip in October.  This is actually a bit smaller than the Amazon hard-sided luggage but we were able to fit quite a bit in it.  And by quite a bit I mean, 2 adult sized dress shirts, dress pants, dress shoes, 5 pairs of socks, 5 pairs of underwear, 5 t-shirts, 5 pairs of shorts, toothbrush, toothpaste, sunscreen, and deodorant.  We still had the smaller outside upper pocket available and the bigger skinny outside pocket with nothing but some paperwork in them.

The handle expanded nicely and seems solid, it can lock at a couple heights.  The regular handle is sturdy and padded.  The wheels are smooth and turn in any direction.  The whole suitcase is light.  The zippers appear to be able to accommodate a small lock as well or luggage tags.  I am happy with this purchase and I'll report back after it get use on a trip next week.

Update:  My 15 year old used this on a trip to Florida and had no problems storing it in the overhead bins on a Jet Blue flight.
