Sleek design and easy to carry. Positive locking mechanism to adjust length and the tube is tough and seems immune to the chaos of air travel and baggage handlers. The top has a good, secure closure. No shoulder strap but the handle is rugged and carries easily. The only real down side is that it requires 2 locks. One to lock the lid (top) and another to lock the catch that adjusts the tube length. I've tried others but this is always my first choice. I liked it enough to buy a second one.
