When you look at the picture that makes it look like it so easy and conveniet WRONG!!!!!!
It is diffcult to get on the chairback straight like the picture, then you tighten the strap around the chair you can never get it tight enough and you end up hitting walls,doors, and anything in reach of the cane when in the holder because it will sage. You are all ways tighten the strap because it comes weak and sages, when I tried to put it on my scooter there was noway it would work good. In final it is not worth the money you pay for it I am sorry I brought it and no longer use it.
