Just last week, 8,258 people got Nomorobo protection!

We love Nomorobo especially when my husband is trying to rest. I have told others about it. Thanks.:-)

Although at first I was leery of installing Nomorobo, it proved its value immediately. The phone rang - once - then stopped. Just as promised. Caller ID showed an unknown number. Since that first call, I can't tell you how many others it has stopped my phone from ringing off the hook. Continuous unwanted calls are quite stressful. This technology works.

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!

Thank you, thank you,thank you. This has been the best thing since cell phones. Having my phone only ring one time brings a smile to my face.

It appeared to be working well when I first signed up months ago. However, within the last 2 months or so it doesn't appear to be working at all. I got numerous political calls just before the election,with none of that nonsense bring blocked, and am still getting calls from some stupid Diane soliciting rug cleaning for which I cannot opt out. What happened to my robocall?

Just one ring and we know Nomorobo is working and doing it's job. Highly effective - great application....

I have been using NOMOROBO from day one. When the phone rings and it stops after one ring, I just say to myself NOMOROBO got another one.I love it and I'm going to download the beta cell phone app and will report how it worksThanks

Outstanding tech. Great to have peace at home. Still start to move on ring one but have learned to wait. Wish I could get rid of the other nuisance calls as easily!!!!
