This percussion massaging device is on sale for less than $100

Cheap massage chairs are a common Christmas gift, but we're willing to bet they don't get a lot of actual use from the people who could really use a massage. We're talking about people with deep, chronic joint pain or anyone who does a serious workout on a regular basis.

For that kind of soreness, there's nothing quite like a hand massager, and the ExoGun DreamPro Percussion Massage Device is one of the best.

For one thing, it's the only unit of its kind that comes equipped with six speeds ranging from gentle pressure to deep tissue relief. There are attachments that allow it to really get in the contours of any muscle and deliver real therapy where your body needs it most - not just generalized comfort.

And while the four-hour battery life is impressive, the exterior design is a real standout. The angle of the handle not only allows you to reach trouble spots, it lessens the vibrations from the motor so you can keep a firm grip.

The ExoGun DreamPro is already on deep discount (almost 80% off retail), but you can take an additional 20% off that final price by using the holiday coupon code GREENMONDAY20.
