Who is this massager most suitable for?

It is highly recommended for office workers who suffer from "mouse hand" due to long-term keyboard use, "phubbers" (people who constantly look down at their phones), sports enthusiasts with sore arms after workouts, and middle-aged and elderly people with discomfort in their hand joints (such as tenosynovitis).
It is especially suitable for those who frequently use their hands in their occupations, such as piano teachers, manicurists, and programmers, for early prevention and maintenance against strain.
