I push the limits my equipment putting 400,000 frames on 5Ds and dragging my gear all over the world. Most everything can survive what I demand. Kata partially sold me on their products with a video on their website that claims military grade quality. This thing has a plastic joint when extended and I broke two of them (at the plastic joint) within a few months. Kata was good to me and replaced it once for free but I broke it again. I had a big well made piece of luggage in this same role that held up against my abuse for over two years, and these carts last me about two months. Granted I am putting a lot of weight on this thing maybe 75 pounds. The only military quality about this thing is the cost.
