I'll state for the record that i love my pacerpoles. But it just seems to be me who has a problem with them jamming. No-one else has to return them once a year for a refit. No-one else has to call upon their good will. So i tried using my dad's vice (no, not his weekly cigarella) padded out. No joy. So i'll need to contact the folk again. Silly thing is that they were fine when i last used them, i didn't use them when i last overnighted in the cairngorms, leaving them strapped to the pack. And now they are both jammed. At different sections. Trust is a dilema for me. They are the only poles that i have used since getting them.
