Such a simple device but man I love this thing.
I actually remember when it first came out and a bunch of Kenyan runners came to the US and lived on the inventors floor and raced all over as Team Stick. Low budget but it got the product some good exposure.
The Stick is made of plastic and you use it to massage your legs, back, neck, or other sore spots. It has some flex and man you can get in deep if you choose to.
Since I have messed up calves with tons of knots I've taken to using the 17" Stick before every run. I work the device over the muscles and get the knots to loosen up and to get blood flowing. What a difference it makes.
Post run I like to use it again to help with recovery and work out any tender spots. I'll work the calves, thighs, hamstrings and around the front of my shins.
Here's some more info direct from The Stick

General Instructions
A typical warm-up for healthy muscle tissue is about 20 progressively deeper passes over each muscle group (about 30 seconds per area).
Discomfort or pain is experienced when the spindles locate a bump or tender knot in the muscle - this is known as a trigger point.
Muscles containing trigger points are often weak, stiff and sore. They are frequently tight, easily tire and often hurt.
Muscles containing chronic trigger points need 20 additional passes over the involved area, and may require attention several times daily.
