Back in February we told you about the Xtensor positioning itself as the solution to BlackBerry Thumb. It is essentially a finger exerciser contraption that is supposed to help promote healthy fingers.
Turns out that Joanna Stern of Laptop Magazine got her hands on one of these Xtensors. She does a great job of explaining how it works in a video on LaptopMag.com.
If you suffer from BlackBerry thumb you might want to check out the Xtensor. On the other hand I always thought that the Xtensor was just a really expensive version of the GripMaster. The GripMaster provides the same type of exercise and it only costs $12 on Amazon compared to the $39.99 of the Xtensor.
Check out the Xtensor video at LaptopMag and let me know what you think!
