It is literally just a little circuit board, which actually makes it way easier to tape under a desk out of sight.

The switch on the side is great because you can turn it off so it doesn't drain the battery.

Verified BuyerYes, it requires manual switching via the onboard slide switch. Simply flip the tiny white switch to turn it on when you want to start the prank, and turn it off again to save battery when you are finished.
It is an exposed electronic circuit board module with visible components, a small buzzer, and a coin cell battery. This raw design is intentional so it can easily slide into narrow gaps or behind objects where a standard bulky plastic case wouldn't fit.
Designed to hide where plastic toys cannot
Bulky novelty gadgets get spotted immediately. Our raw exposed circuit board slides effortlessly behind objects out of sight.
Common questions answered
Everything you need to know about hiding and running your prank gadget.
The lack of housing is intentional so it can slide into tight spaces, behind objects, or inside everyday items where a bulky plastic case wouldn't fit.
Because it's small and emits high-frequency chirps, it tricks the ear into misidentifying the direction, buying plenty of time before anyone locates the source.
It runs on a standard, easily replaceable CR2032 coin cell battery, and includes an explicit manual ON/OFF switch so you can turn it off when the joke is over.
It operates independently without tying up your phone or requiring Bluetooth connections.
Simply flip the onboard slide switch to turn the unit on or off whenever needed.
