I've hiked with them 4 times now in Red Rock Canyon, Nevada, and they have been outstanding. They were easy to set up and lock my desired position into place. They stay locked for me, no problem. The carbide tips are amazing, and can grip on a sandstone rock at a 45 degree angle and hold me coming up as well as going down. They've taken me from "can't hike anymore" due to an injury to being able to hike again - on moderate trails!
I've taken to using them during walks around my neighborhood and I've went from walking 1.5 miles after 6 months of physical therapy to 3 miles, no problem and no pain, in the last 3 weeks.
These inexpensive little sticks gave me a part of my life back. I can see myself wearing these out. I absolutely love them.
Just bought a set of these walking poles. Used them for 1 1/2 hours walking on snowy/icy sidewalks. They did great. You can remove the rubber tips to expose ends that are great for snow/ice/dirt. They are very easily adjustable. I look forward to using them for hiking as well as regular walking.
Poles have NO instructions. Rotate shafts counterclockwise wise ,lefty loosey. Extend to correct length, chest height and righty tightly,clockwise To lock in the correct lenght. Notice there is a locking snap when tight enough, this makes the shock spring locked and the shaft full stiff. Trun counter wise loosen just enought to fell the shaft unsnap to have the poles engage the shock spring into action.. Work with them and you will figure it out !
