This is a decent piece of luggage.  It can be carried on your back fairly comfortably and stuffed very full with an amazing number of items for a bag of this size.  As long as your plane isn't super full or the airline attendants overly observant you can probably get away with stashing this in the overhead bin no matter that it will be larger than airline carry on regulations after being overstuffed.  I haven't had the bag that long and I would say it is of average quality construction but I don't expect it to last indefinitely especially as I have a tendency to strain my bags through over packing.  Overall it is an OK piece of luggage and if you can buy it for $75 (or less) at a fair price.  If you don't plan to wear it as a backpack you would probably be better off with a wheeled carryon bag.
