This is a device that is evil like no other.It will quietly play one of several startling sounds like something unsettling creaking, unidentifiable scratching sounds,gasping last breath,sinister child laughing,eerie whispering of ‘hey, can you hear me?’ and more.The human is weak and nothing is scarier than one’s own imagination. They will get crazy, thinking they are communicating with the dead or loosing their mind. Perfectly suitable for dorm, office, home use or even someone’s car.
