It might be better than the Pressurepointer that I bought. Cheaper for sure pressure pointer was 79..00 in 2004.

the pressure pointer had wooden balls that were kind of slick and not grippy, so they would slide off the spot. and the wooden tips were too hard to be very comfortable.

I think something that is more like a finger, thumb or knuckle texture/pressure/size would be best.
I don't know if thera cane is hard plastic or with some give to the ball areas.
