The report
Two cases, bought retail, loaded to 40 kg and moved through twelve simulated flight cycles plus 900 km strapped to a pickup bed.
The seal and the latches are the reason to buy this. Ten loaded drops from 1.2 m and every latch held. Submersion produced nothing inside either case.
The wheels are the weak point. After 20 km of towing over broken tarmac one bearing developed detectable play. Replacements are $18 and take four minutes, which is why we still rate it repairable.
