I have a few sets of Peerless, and my newer hinged 801s have started to loosen up to the point that if I apply the single strand part of the cuff to a persons wrist, it swivels through it's motion but doesn't go into the slot to engage the locking mechanism, it just bounces off the base of the double strand (does that make any sense?). They were still perfectly useable, I just couldn't rely on them to engage if I had to snap them on a guy's wrist in a fight or something. I sent them back in to Peerless under their lifetime warranty. 6 days later, they were back, fixed; and they sent me a brand new pair of 801s for my trouble. So for the cost of shipping there ($4), and a 6 day wait, I got essentially two new pairs of cuffs. Props to them for being fast, honest, and generous. They actually could have dishonored the warranty because I have my name etched on them and that voids the warranty. The only other LE equipment company I've had repair work done by that is as good is Streamlight. Both of those companies now have me as a customer for life.
