I had a folding walking stick that I seem to have misplaced during a move a few years ago. Because of recurring back pain, I have been thinking about buying a new one to keep in the car in case I have a flare-up away from home. An offer to try the Switch Sticks Folding Walking Stick seemed like a good opportunity.
This is a well-designed and well-made folding walking stick. It comes with a storage bag, a hook & loop strap to hold it in the folded position, and a sturdy wrist lanyard on the handle. It is height-adjustable to accommodate most users. It comes in at least 20 designs that should satisfy most customers. According to the manufacturer's web site, new designs are introduced twice a year.
Taking off the strap and shaking the cane slightly will let it snap out to full length. Once it has unfolded, there doesn't seem to be any easy way that one of the joints could come apart or collapse. It has a good, strong feel that seems quite reliable. Over the course of what should be many, many years, the elastic cable that maintains the tension might lose its ability to hold the sections tightly in place. At that point, you would want to replace the stick.
