I love NOMOROBO!! I hear and see the calls coming in and in an instant the calls are blocked and I'm not bothered. I'm signed up for all the DO NOT's and NOMOROBO added more peace to my life. Thanks so much!!

I absolutely love love love love love this service!!

It is wonderful. I smile everytime a call gets bounced with only one ring. I love this service.

I think it works great! One ring and the call is dropped.

Overall I am very happy with your service. However, I want to point out that it is not 100% effective. Specifically, during the election season from about September through the election in early November, we noticed that robocalls for political surveys frequently got through your technology. Of course, now that the elections are over, we are no longer being bothered. But, is there some reason why those calls could not be stopped?

Do not bother to register your phone numbers with the national do not call list. NOMOROBO actually works. Really glad we signed up for it.

I am amazed by the number of calls that are blocked.Is there any way for me to submit a suspect number?

The best caller blocking service I have found.
