AnnoyingPCB Beeping Prank Device - Small, Annoying Noisemaker, Super Long Lasting Battery Life - Won't Stop Beeping for Three Years, Gag Gifts, Pranks for Adults

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.

3 meses con el y ya no funciona

Left this hidden in a piece of decor at my sister's house with the sound most similar to a smoke alarm. I came back a little over a month later and saw a smoke alarm hanging from their ceiling. When I asked about it she told me the story about hearing the chirp for weeks, her boyfriend changing all the batteries in every smoke alarm in their house, then changing every smoke alarm with no luck. They spent over $100 on new smoke alarms and were losing their minds. I have never laughed so hard. Forwewarning, don't do this unless you know you're loved because this is the kind of thing that will make people hate you.

Lasts seemingly forever on 1 battery and is very annoying and small. 5 stars.

Fun gag for everyone but your targets. Just enough beep to drive your friends crazy. My only complaint is that it beeps when you turn it on, and it beeps as you go through trying to select a tone, so you really need to plan your prank ahead of time. Durability could be better, battery no longer stays in, but it worked once and that's good enough for the price.
