With all that's going on in the world nowadays, you don't to need to be wearing a tinfoil hat to understand that your privacy might not be as private as you would think. Perhaps a phone encryption device might be just what you're looking for?
With the Secure Phone Miser (well, at least two of 'em, since the encryption is dependent on both ends of the telephone conversation having a unit installed in order for it to work), users configure the device with one of over 1 million unique codes, allegedly making your phone conversation completely immune against things such as phone taps. In the event that you need to talk to multiple parties simultaneously, the Secure Phone Miser supports up to 10 links, conference call style. Of course, it only works with regular telephones, that is, not cellphones.
LEDs and audio tone signals let you know whether or not a call in properly encrypted and the optional 9V battery lets you become a mobile Artful Dodger.
You can grab the Secure Phone Miser right now for $239, and $195 for each additional unit (remember to grab at least two!), which is still significantly cheaper than other encryption devices we've seen on the market.
