The best way according to me, to test a device like this, is to "torture test" it by using it. So I used it at work and at home. I used it while surfing, gaming, writing this article etc. At work I used a regular Intellimouse and at home I used a Boomslang 2000. Click here to read the review.

One of the first things that I noticed was that the efficiency of the mouse Bungee depended on your sensitivity of the mouse. Less sensitive mouse setting means wider movement and vice versa. When you move the mouse widely there is a greater risk that the mouse cord gets in the way. There is where the Mouse Bungee is doing most sense. Also when using the Boomslang which has more sensitivity the Mouse Bungee helped to increase the precision. Which made it a little more comfortable to work or game with the mouse. 

So doesn't it get harder to "steer" the mouse with that springy arm attached to the cord? Frankly no, you can hardly notice the arm. There is a perfect resistant in the arm and all it does is keeping the mouse cord out of the way. However I noticed that the Mouse Bungee maybe should be a little bit heavier. When I tested it with Counter Strike I noticed that sometimes it moved when I made sudden moves with the mouse. But that's basically it.
