I'm happy with the weight, feel, and ease-of-use of these poles.
I'm not so sure about the durability. On my first outing, the tip of one of the poles broke off. Montem said that was NOT typical and quickly sent me a replacement pair.
On a 90-mile hike of the Appalachian Trial NOBO through MA (CT to VT), the plastic locking nut on the adjustment lever proved to be a weak point. One fell apart and broke off. A second cracked. (There are 4 in a pair of poles). I had to resort to duct tape (fixing one of the pole segments) to finish the hike.
Once again Montem Customer Service was responsive. Unfortunately they don't have any replacement locking nuts, so they mailed me another set of poles. CRAZY. And actually not very helpful for field failures - I want a small supply of locking nuts with me so I don't have to duct tape in the field. So, I went and found that a 5mm wing nut (see photo) seems to work well as a replacement, though I haven't yet tested it in the field to confirm that it will not loosen up during heavy use.
