I travelled with this less than half a dozen times and now the retractable multistage wheel handle has become stuck and unusable.  The time this occurred I was about to pass through airport security to board a flight and had to hammer it in to retract it before I could place it on the x-ray conveyor belt.  The laptop sleeve buried at the bottom is also not a good idea as every time I pass through airport security I have to dig my laptop out from a pile of clothing.
