Looks like a simple device. But I'd think by knowing those pressure point locations, that could be accomplished with thumb pressure while wrapping your palm and fingers around the rest of your arm. I had a little training in school and have been doing self acupressure with some fascia manipulation. It really helps with my old age aches and pains. But I haven't had arm pump problems since I was a kid. Maybe no muscle remaining to pump? Lol!
