I travel on the train with my cameras and laptop. (3 leicas and accessories) I felt very secure this time because my new case is strong and locked. It also fits in the bag area above my seat. I take a heavy duty cable lock to lock it to the train when I go for meals. Much less hassel than taking it with me.
The first one I got was broken out of the box, then i returned it and the second one came out defective as well, but then i was not in the country anymore and could'nt return it again. I've had this case for a year now and I can barely use it anymore, several parts broke and the handle doesn't pull out anymore, etc. and i haven't used it that much. It looks very stylish and cool, but for what it costs, it should be much better constructed than it is.
I purchased a camera backpack to alleviate stress from a shoulder bag, but this wasn't a great solution. I then saw a Porter Case demo at Photo Expo and was sold. The fact that the Porter Case also turns into a hand cart is an amazing feature. This case should be in every photographer's inventory.
