Input:
I got the TeleZapper when the "Out of Area" calls on our Caller ID hit 13 in one day. I bought it and kept it on our phone line, following their directions for 4 weeks. We're now up to 20 in a day and the TeleZapper has been returned. I bought mine at Best Buy and should have gotten a hint from the fact that all of the TeleZapper boxes appeared to be taped (e.g. returned and repackaged). At the exact time I returned mine, someone else was also returning one. My advice to you is, don't bother.
