FANTASTIC! My only problem is that I accidentally blocked one phone number. It would be helpful if I could unblock ALL numbers I have blocked and then start all over again.

Great service!

It's the best.....so many calls with only one ring and then GONE!!!

Nomorobo is a terrific product --- says what it does and does what it says. I'm delighted with the results and have recommended it to several friends and family members. The only thing that could possibly make it better would be if that single ring could be eliminated although I realize that might not be technologically possible. Plus then I'd miss out on the immediate satisfaction of knowing that another phone scammer had the electronic door slammed in their face. :-)

GREAT

My husband and I do a "happy dance" every time we hear 1 ring and then it stops. We smile and say "Nomorobo is working again"! I even put it on my 87 year old mom's phone line. She doesn't quite get how it works, but I'm at peace knowing she's not getting those annoying calls anymore. Thank you, Nomorobo!

We laugh and celebrate every time the phone rings only once. Nomorobo is fantastic! Thank you for giving us this peace.

Before Nomorobo we received 20+ calls daily wanting us to buy, try, or use junk. Now those calls have been cut to 5+ a day BUT they only ring twice!, We now visit, eat meals or watch television in peace.Thank you.
