So these are the second pair of trekking poles that I have owned, the first set was a hand-me-down pair that broke on the first use. I didn't use poles for years but then I had a slight knee injury and didn't want to give up on weekend day hikes so I bought these pair of poles. I owned a few things from Wildhorn and decided to give them a try. I decided on carbon fiber vs. the aluminium just out of durability. Don't get me wrong my knee still has pain, really my own fault, but these poles delivered on what they were supposed to do, provide anti-shock and traction for the trail. I thought at first that the locking system on the adjusters were a bit weak but they have never moved and have stayed solid. And let's be honest the green color is pretty awesome. I do like that it came with different tips depending on what trail I hike that day. Good buy!
