A few weeks ago i bought a XP1 because a lot of people told me that it was difficult to pick. And he told me that only a few people picked this lock. So i started trying.
Maybe you could figure out why and get kudos from the company for telling them, like the legendary toool club did for Lips locks in holland.
er, nah, corporate gratitude is and oxymoron, forget it.
btw i`m also a member of toool.
But the difficult part of the XP1 is the weird profile. As far as i know.
The balls are only a copy protection, so that should be no problem.
