Bests & Worsts Reviews from Amazon

Although I'm on the don't-call list, I still get hammered with junk phone calls, several each day. I got a Panasonic answerwing machine with a phone blocker, but it didn't help much. The block list was only 25, and the phone still rang, though only once. I got this product and hooked it up to the answering machine. Now, I can block virtually limitless calls, and the phone merely chirps when a blocked caller rings. Very easy to use: Plug it in, and set up the date and time. It starts working immediately. When an unwanted call comes, push the left arrow, and then the Blacklist button. They'll never bother you again.
