Funny name, genius product. This incredible device slightly totters on your the trackpad of your laptop, ensuring that your computer stays out of hibernation mode. The gentle movement of the mouse is enough to keep the machine awake and your messaging apps set to "online" (wink wink).
The Jiggler is 100% undetectible, as it runs on a battery. Just flip the Jiggler over and it will start rocking. When you flip it back it stops the motion.
Now you can be idle while your computer makes you look "active". Brilliant.
