TeleZapper TZ 900

Summary: It Works (mostly)
Review: We've noticed a significant reduction in calls in the first four weeks of use. The beep & the dead air (after a call is zapped) is a little annoying, but the beauty of it is, after a while you just don't get as many calls! So it stops being an annoyance, I guess. Companies that don't use auto-dialers still get through, but they are a tiny minority of telemarketers.

Not perfect technology, but a vast improvement over three calls during dinner.
