Just last week, 8,252 people got Nomorobo protection!

For my wife and me, it's an invaluable service. We are bombarded by robocalls, and Nomorobo filters them out very effectively. Thank you, thank you!

Love it cuts off so many of those calls. Thank you

Even when an occasional robo call gets through, I really get satisfaction in reporting that number. Most times, however, after 1 ring these calls go away! I'm loving this...couldn't be more pleased!

I think it is fantastic and it has quietened the phone calls almost to nothing even during the election. Congratulations on a great tool for stopping mid-meal, mid-viewing extremely annoying robocalls. Combined with my 'no call" list peace reigns !! Thank you so much.Any charity you would like me to contribute to on your behalf ??

We signed up for Nomorobo on our 2 landlines as soon as it became available to us, which was a little over a year ago. We cannot thank you enough for making our home robocall-free. We absolutely love the service. Every once in a while, a robocall gets through, but that is rare. On 2 phone lines for more than a year I think maybe a few calls got through. We are totally satisfied with Nomorobo and I have recommended it to others. I am looking forward to the day when this service is available on cell phones. Thank you so much for being innovative enough to have developed this service.

I probably will not recommend this nomorobo. The service seems to also blcok calls from other numbers that may have been okay to accept.

The only way to describe it is GREAT. The best thing ever!

It's great. It doesn't catch everything, but it certainly does catch it's share. I am sure that you will improve as time goes on and I intend to continue to use it. I have recommended to many people.
