First of all I want to thank everyone at this company for all of their help and excellent service. I purchased these poles with safety and comfort as priorities. These poles are well worth every penny. Both upper and lower locks are FlickLocks and they hold and I mean HOLD. If they did not, I would either be severely injured or the worst that could happen. A sudden high gust of wind, which is common and to be expected, hit while in a canyon and I struck these poles hard and often against the rocks for stabilization and they did not collapse or give at all. The carbide tips are outstanding. The anti-shock system on these poles are whisper quiet. There is no "bounce back", no rattling or clattering. It is a comfortable system and yet a very stout system. It is plenty stout for uphill traversing and very smooth downhill. It does not turn off. Some people like the on-off but this is the best and most comfortable, yet stable anti-shock for all purpose use that I have used. Personally, even if it did turn off, I would leave it on. The baskets are small but they are tough and work very well. I am hoping to find more in this diameter. These poles may weigh a little more, keep that in mind, but you will be getting some excellent poles. The excellent personnel will be more than happy to help you with any product that may suit your particular needs. Give them a call. I did.
