Bought a Monadnock baton off an INGO member that was very difficult to extend (which was fully disclosed by the member) because it was super cheap; figured I could repair it, or smooth out the action somewhat - but it's pretty much a sealed unit. So I called Monadnock and they told me to ship it in. $2.95 worth of postage and 10 days later I have a new one, courtesy of Monadnock/Safariland's Lifetime Warantee on batons!
