Have been using 2 hand canes and needed more support for my wrists/shoulders.
These are very solid, sturdy feeling and comfortable. Only issue is the bulk and weight of the arm carrier.my shoulders hurt with carrying /lifting these. Bulk also makes using them in the car ( going someplace with them), or holding both together to make full use of a hand... They don't " nest" or self adhere to make more manageable, although they do fold compactly and have a nice storage bag.
Only other concern is no secondary barrel compression nut to secure length- only the sliding button adjuster. I anticipate with use they will start to creak and move at the adjust point.
