The Prank Device That Won’t Stop Beeping for 3 Years

Bought for April fools day joke on boss! Hid it in his office, he had no idea where the sound was coming from. This is tiny and easy to hide. Sound quality is great has different volumes easy to adjust. Multiply sounds to chirps to choose from. Good battery life. Left it in his office for 4 days before telling him! Fun for adults! lol!

In the midst of a prank war or if you just want to give someone a real startle, these prank devices are the perfect tool. Their small size means they can be hidden almost anywhere, making them ideal for a stealthy operation.What I particularly love about these devices is the ability to change the chime speed. This feature allows for customization based on your prank objectives. For a quick, irritating prank, speed up the chimes. If you're aiming for a long-term, slow-burn kind of prank, keep it at the standard setting.I tested out these devices by placing two with altered chime speeds. The result was hilarious – the targets were absolutely bewildered for two whole days trying to locate the source of the noise. I believe if I had left the settings standard, the confusion and hilarity could have lasted for weeks!These prank devices are absolutely worth the investment if you're looking to pull off a memorable joke. They're effective, easy to use, and provide endless amusement.

Where to start...I purchased this to prank my office staff. The ladies in the office are a ton of fun, always joking around and having fun, and absolute rockstars at their jobs. They're meticulous and detail oriented, not much gets by them...The kind of environment you enjoy working in, work hard play hard. Enter the little tiny noisemaker. I hid it in a decoration located centrally between the 3 offices, but closer to 2 of them with the beep muffled ever so slightly by it's hiding place. The hiding place was key, due to the short duration of the beep which sounds like a smoke detector alert, it makes the sound very non-directional and hard to pinpoint. That combined with the logic in the board that guarantees there's no rhyme or reason to the frequency of the alert made for the perfect 2 week run of mayhem.It started out as a minor annoyance, but the search escalated quickly. I of course helped them look for the mystery beep, pulling down smoke detectors, checking batteries, unplugging appliances that might possibly be the source. Nothing seemed to help. I checked in with them periodically to see if the noise had abated and even suggested a couple times that they may just be imagining the beep. They started recording the times that it would beep, to try to decipher a pattern that might lead to solving the mystery. I encouraged and supported their efforts the whole time, being as helpful as I possibly could!I announced my prank in the weekly company meeting which got a ton of laughs, and am now walking on pins and needles because I know retribution is coming my way...100% worth it! Do not use this on someone if you're not prepared for them to plot revenge.I can verify that the beeping is as random as could be for anyone that needs to explore their diabolical side, this is a great way to go.5 stars, highly recommend.

Sounds quality is good but only loud enough in a quite environment. So far battery is good and functioning as it should. You never know when it's going to go off so if can drive people crazy! $14 of a little high. If the battery didn't last I'd return. Descent value.

Perfect little prank machine. Works even better when you hot glue a magnet to the back! But you didn’t hear that from me.

I've purchased the annoyingPCB and other off-brand products a couple of times, and they sure do their job annoying people. Although I really doubt it lasts 3 years, mine stopped working after a few months, although it might have to do with the environment, maybe leaving them in a car during summer fries the system.

All sounds have a computer generated sound...the cricket sound is more like what you hear when the battery is going dead in a smoke alarm...my wife even said the same thing...I said it's supposed to sound like a cricket and she said...fail on that one. Disappointed in the purchase.

If you want to disrupt work, this will do the trick. I set it to mimic the sound of a smoke detector when battery needs replacement. I placed it under a bed of pebbles which housed fake plants at work. It was also under the smoke detector. It caused enough confusion that my coworkers kept looking up at the smoke detector when it was really right under their nose. It caused one of them to call maintenance. I took it out the next day. Will wait a while before I do it again.
