The anti-shock piece in my Leki Super Makalu finally failed, after 10,000+ miles. Leki was happy to warranty it, and shipped me a new section at no cost. A few hundred miles later and the same thing happened to my other pole. I contacted Leki again and they once more said they would happily ship me a replacement section, but that it is on backorder presently. If anyone has an old Super Makalu pole around, I'd love to purchase it from you.

Oh, and in case it wasn't clear from the above, Leki's warranty is absolutely fantastic. Dealing with their customer support staff is pleasant and professional, and they couldn't have treated me better. I know they will come through again, I'd just like the part sooner rather than later.
