The locking mechanism on one of my Leki Ultralite Ti Air Ergo poles failed on my first trip with them. When I returned them at REI, the salesman said someone else had come in earier that day with the same complaint.
I'm thinking of ordering another pair since they're such a good set of poles otherwise. Especially the weight at 14 ounces/pair, you can't beat that. But I don't want to have the same problem again. Anyone else have this problem with the locking mechanism on these poles?
