Been using mine for 1 month now and have put it through some hard use and it has held up nicely.
Took it to Cambodia, Egypt and Thailand.
No issues with the handle or wheels so far.
Zip seem hardy.

I purchased this as a scuba dive bag, but it doesn't feel strong enough to go in checked baggage and too big for carry on. Ok for car or boat though. A nice piece of luggage, great wheels. If only the construction was closer to suitcase material than plastic bag material.
