This is my first pair of trekking poles, nut so far I like them. They are very light, which I think I'll appreciate when I take my big 18 day trek in November in Nepal. They fold up and reassemble very easily. I've used them on 10-mile hikes but fairly level terrain, just to get used to them, and it has gone well. I've not stressed them, so I'm not sure how durable they are, but so far, I like 'em.
