I've just started using these poles, but I'm very happy with them so far. The claimed weight is right on and they are very solid. I'm 210 lbs and often carry a 30 lb pack and these poles feel quite sturdy and the twist locks have never slipped on me. The locking mechanism was a little stiff at first which made adjustment difficult, but after a little use they work great.
