Just last week, 8,261 people got Nomorobo protection!

I think it's great. I tell everyone how well it works.

I love this service. It blocks so many of these robo callers. I laugh at the tricks these callers use to disguise themselves. Nomorobo helps me a lot.

it helps but the fact that my phone still rings once can be annoying late at night. Also MANY calls are still coming thru> The stupid cable company ( Time Warner) ALLOWS unidentified calls even tho I have blocked them as they consider " name unavailable" to be an identity!!!!!thnx for all you are doing to try to knock off this nonsense! I did not have this kind of trouble with phone calls until we switched to Time Warner!! and yet we pay $2 to be unlisted..... what a waste!

Works great! Wouldn't be without.

This service has been great. Stops the PIA's (Pain in the ASSES) from getting through. They get smarter and a few are finding how to get around it.

Hey, what is that sound? Silence; life is good again without all those annoying calls ringing on my phone.

Until we signed up for Nomorobo we were plagued with solicitation calls. Although they still call we no longer have to look at caller ID to determine whether we needed to ignore or answer.

It's such a relief when the phone only rings once!!Many thanks for this great public service.
