I just flew international Shanghai - Vancouver - Shanghai with my MVP, Hammer, iClear 30's, and Protanks. No problems at either end. Even forgot to take the liquids bag out of my backpack coming back to Shanghai. Nobody looked at my gear twice, altho there was a bit of consternation in Shanghai when I brought a microcomputer back to China (8"x5"x2"). They'd never seen a computer that small before and wanted me to turn it on for them. I said sure, as long as you provide me with a monitor, mouse, and keyboard so you can see it's actually a computer and not a bomb. They couldn't be bothered to loan me the equipment and let it thru anyway. LOL
