Product Description
The Digital Speed Meter works with the Dyna-Flex PowerBall & Pro Plus models to display speeds and remember your best speed. It easily adapts to the unit -- simply remove the cap of the gyro and snap the Speed Meter into place. PowerBall & Pro Plus sold separately.
Amazon.com Product Description
Designed to work with the DynaFlex Pro Plus and Powerball gyros, this digital speed meter upgrades the performance of both machines. The speed meter offers three important functions: it measures the user's current speed, remembers the user's highest rpm, and calculates the maximum revolutions of the gyro. As a result, it's possible to keep precise track of your rehabilitation progress, or you can challenge yourself or your friends to see who can achieve the highest speeds. Plus, it's a breeze to install the speed meter--just remove the cap of the gyro and snap the meter into place.

Its a great product. It keeps track of my progress so I know that I am actually improving. You can do without if you don't care about knowing the exact rpm and improvement. I personally like to know how much I improve.

My wife and I are computer engineers and we type a lot every day. This little toy gives us lots of funs and exercises our fingers / writs / forearms.
It's very easy to start the gyro with the attached red string, and I don't have any issue mentioned by other people that it's hard to start. I think maybe they don't follow the instructions somehow?
