I got one of those devices recently, but had to return it. Set it up, and it did not work as I hoped it would. Comes with itty-bitty cord you hook into your phone jack. No good. Maybe I have to invest in another kind. The TeleZapper proved to be a piece of nothing; it may as well not have been there. They now make phones with call-blocker technology, and all phones should have this, if it works like it's supposed to.
