In the past few years, we have covered plenty of neck, back, and leg massagers here. The Breo WOWO S Electric Hand Massager is also worth a look. It uses 5 independent air bags to work on your fingers, palm, and nails. You can customize its settings on your smartphone.
The device has 5 massaging modes and 3 strength levels. It uses air pressure and heat compression to knead your entire hand to get rid of any soreness and stiffness.
