Flippin' Phone ranks high on the scale of easy, zero damage, memorable pranks. It is a small, slim device that emits an annoying whistle-type ringtone or notification every 10 minutes. The best things are its small size, which makes it hard to find, and the extremely realistic sound. Flippin' Phone is suitable to prank friends, neighbors, or family, especially those you don't share living quarters or a workspace with. Just activate the device and let your friend find it. Or move it around from time to time to really aggravate your parents. Or have it nearby and pretend you don't hear it. What will YOU do? Upload your shenanigans and tag @FUNdeliveryUS. We also offer a meowing cat (Meow Hear This), a chirping cricket (Frickin' Cricket), a NEW fart trio (Yeww Farted), a low battery smoke alarm (Bleepin' Battery), and a crowing cock (Rooster Sucker) as pre-programmed hidden annoying sounds and Annoise, a device where you can record your own sound. Tips for success: To turn on, press the black button. You will hear one beep to indicate the device is on. (If you don't contact us immediately for some replacement batteries.) The batteries will last for about 3-4 days if left on. You can always replace them if you need more time. Press the black button again to turn off (listen for two beeps) and save battery life. Contains one device, 8.3 x 4.2 x 0.9 cm Includes three 1.5V batteries (AG13) Made in China
