Q: Compared to single-part massage devices, what advantages does this one have?

A:

With the price of just one device, you can take care of your hands, arms, and wrists. There's no need to purchase separate devices, which saves a lot of money!
Moreover, it is designed with different functions for different parts (for example, focusing on heat for the wrists and pressure for the arms), making it more precise than the "one-size-fits-all" massage devices.
Customers who have used it all say, "It hits the sore spots!"
