Just last week, 8,271 people got Nomorobo protection!

Excellent service. Thanks a lot.

Very good blocking service. Still have issues with several annoying solicitors who manage a bypass.

Overall good service. Would be better if four-digit Caller ID numbers could be blocked. Would be much better if the phone didn't ring at all on a blocked caller, instead of allowing one ring.

While a few of these pests still persist, Nomorobo has made a big difference in our household. Thank You So Very Much!

Neatest thing since sliced bread.

I love it! Fingers are crossed for an enhanced version allowing users to interact with a Nomorobo database to manually add numbers that slip by your filters.

I LOVE Nomorobo. I get a tremendous amount of satisfaction every time I hear my phone ring ONE time - knowing that another rude, ignorant, scamming person has been foiled in their attempt to get to me! Thank you, thank you, thank you!
