The black hand and the black cat and dog work on every laptop trackpad and touchpad, Dell included. The finger works on MacBooks and most Windows laptops, but not on Dell — Dell trackpads sense touch in a way its arm cannot trigger. If you are on a Dell, choose the hand, the cat or the dog.

There is nothing to detect. No USB, no Bluetooth, no software, no driver, no admin rights. The device never touches your computer. It works entirely on the outside, moving your mouse or tapping your trackpad the way your own hand would. There is nothing installed for IT or security software to find, because there is nothing installed.

No. Drop in the AA battery, set it in place, and it runs (AA battery included)

No. Nothing plugs in anywhere. One AA battery powers it, and the battery is included. No USB cable, no charging cable, no adapter, and no port on your computer used up. That is the whole point — your work laptop stays untouched and your desk stays clear.

It depends which mechanism you have. The always-on star runs 12+ months, because it uses a quartz clock movement, the same as a wall clock, which draws very little. The trackpad jigglers and the mouse jiggler with the switch use a DC motor and run 3 to 6 months at normal use, which we measure as two hours a day, five days a week.

Almost always because it was left running. The trackpad jigglers and the switched mouse jiggler have an on/off switch for exactly this reason, and three to six months assumes you switch it off at the end of the day. Left on around the clock, it will run down in weeks. If you have been switching it off and it still drains, call us — that is a warranty matter, not a battery one.

Every model is silent in normal use.

A mouse jiggler sits under your mouse and moves it. A trackpad jiggler sits on your laptop's trackpad and taps it. If you use an external mouse, you want a mouse jiggler. If you work on the laptop itself, you want a trackpad jiggler.

If you work on the laptop's own trackpad, including any Dell, choose the hand, or the cat or dog. If you work on a laptop trackpad that is not a Dell and want to spend less, choose the finger. If you use an external mouse and want to switch it off at the end of the day, choose the one with the on/off switch. If you use an external mouse and would rather forget it exists, choose the always-on star, which runs over a year on a single battery.

The trackpad jigglers and the switched mouse jiggler have an on/off switch. The always-on star does not — there is nothing to turn off, which is the point of it, and why one battery lasts over a year.

For the mouse jigglers, yes. Optical or laser, wired or wireless, any brand. If your mouse works on a desk, it works on ours.

It slides a plate carrying an optical pattern underneath your mouse, which produces randomized, jagged cursor movement rather than a repeating loop. Motion that wanders looks like a hand. Motion that repeats looks like a machine.

A USB jiggler plugs into the computer you are trying not to touch, and software jigglers install on it. Both leave something for IT to find, and on a managed work laptop a USB device can be blocked or logged. Ours is mechanical and external — it never connects to anything. It is also patented, built in the United States, and backed by a one-year warranty with a person on the phone.

Designed, manufactured and assembled in the United States, by the two of us in San Diego, California.
