This version of Pocket Cane requires the length adjustment clip (provided in the package) for the one time desired-length adjustment. Please remember to follow the set up video guide (the video guide is within this listing too). It is not the traditional cane that you buy or see in the market, so it doesn’t operate the way like others. Should you face difficulties to understand the video or user manual video link, please feel free to contact us, so we can guide you step by step. Made by high grade aluminium alloy to ensure extremely lightweight (0.33 kg / 0.73 lb) and high strength (workable for user weighs 220 lb). Ergonomic design hand grip with reflector to enhance safety. Maximum length is 94cm (37″), workable for user that is 6’2″ tall (but also depends on your arms and legs length). It can be minimized to only 14″ for easy storage; Ideal size to fit into a handbag, backpack, airplane seat pocket, hang on table edge etc. Most of the buyers followed our guide on video and love the cane so much. But minority of the buyers tried to figure out their own wrong way. If it is that simple, I am sure all the canes in the world would have the same function, but not.
