Quad Cane with Extra Handle

The cane was for my mother. She loves it. The extra handle greatly assists getting up, it is lighter than others. The stability is excellent..

I liked it for some things, but it’s a bit heavy for me. So if I need to go quickly I’ll use my regular old cane.

I like it because it seems to give my family member more stability when walking. She is unsure about the 2nd handle though. How much weight can the 2nd,lower handle hold?
