Just got back from Southern Africa, where I took it from the US to 6 countries without any difficulty. Took it previously to the Pyrenees in Spain, and before that many countries in East Africa without difficulty. Carried 2 or 3 Canon 1D bodies, 70-200 f/2.8, 100-400, and multiple other things. This last trip also carried a 60 Urban Disguise 60.
No problems. The backpack with gear was over 10kg, but it looks small so wasn't weighed. As far as theft, nothing that not in armor is secure. Use common sense.
And I just looked and it's on sale for $195!
It's wonderful!!!!!
