Just wanted to thank your company for your excellent customer service. Initially I thought that I just needed a new clamp to keep my hiker from collapsing. The USPS lost the first shipment you sent to me. You resent my order again which arrived in a timely manner. Then I realized that the actual problem was a broken extension part on the end of the middle section. My fault entirely on that one. Although initially sold out, a few days later I ordered this section…it arrived…and finally, my hiker is repaired. Thanks for all of your assistance! Love these hiking sticks and happy to have them back to normal!
