Despite weighing only a pound, it really packs a punch, delivering up to 40 pounds of pressure through multiple speed settings. It comes with a mini carrying case that houses the blaster and four different massage heads for organization and easy access. It’s also really quiet — a key feature that makes it an ideal product for on course use. You won’t have to worry about disturbing your playing partners as they prepare for their upcoming shots. In fact, they’ll probably be asking you if they can give this a try, too, after they see how much it improves your game!
