Works great!! After using it on my line I placed it on my 86 year old fathers phone and if the phone only rings once (which happens often) he knows its a telemarketer

What a blessing during the recent political campaign!!! It is also useful for senior related calls such as home security and "I just fell and can't get up" scare tactics. I recommend to everyone who complains about robocalls.

This service has made a difference in my life. A lot of unwanted calls aren't coming through.

Overtime the phone rings only once, we all smile and go back to our quiet meal

The best caller blocking service I have found.

Love it! Absolutely love it!! Thank you for creating it. I have recommended it to family and friends and they have thanked us.

Filters out a lot of calls after the first ring. I love it.
