Yes, right you are - now there is plenty of devices which perform similar hush-hush functions. But... they somehow remain mainly unknown for the wide audience. Here, however, the Paranoya creators have decided to make the safety trend the main trend - and so they have focused all the purchasors' attention upon just one point, which eventally was reflected in their device very name (that is, Paranoya) - what inevitably makes this device look different in its buyers' perception!
