I will answer my own question soon by weighing my equipment, but this seems almost too robust. It's marketed as a carry-on for air travel, but as of 2013, the weight limit on such a piece is 18 pounds (~8kg). However, the piece itself is spec at over 13 pounds with dividers. Only hold 5 pounds of equipment if you're traveling by air!
Has anybody had an issue with this?
I've travelled to Europe and the Far East and all over the USA as recently as last month, with my d800 d 300 cameras, 70-200, 500, 28-300 and 16-35, one flash unit, battery charger, ,batteries, filters, my IPad and other small accessories, never even had to open it up, not once. I have carried it on every time to date, but I do have TSA locks so if it has to be stowed at the last minute at the door, I can lock it...although I wouldn't be happy.
This case is rugged and very stable to roll, it never tips and stands a lot of rough treatment.
