Since image stabilization systems work best with rotational vibration, translational vibration can still create blurry pictures. By restraining the up-down left-right and back-front axis, you can lessen this vibration. Since with this design you still have rotational freedom, you can pan and follow something such as a bird or sports player. You can also recompose your shot with little trouble. Of course this technique also works well with non image stabilization systems.

-Hard to break
-You can use this where tripods are disallowed (such as museums)
-If the "tripod" gets dirty you can throw it in the wash
-If you misplace it, you can make another
-Rotational movement still available for panning and recomposition
-Does not hold as steady as a real tripod
-You can get some looks while using it
