Just last week, 8,263 people got Nomorobo protection!

LOVE Nomorobo. Nearly went crazy from robo calls. Now life is serene. Works unfailingly.

Great for those calls that it actually stops coming through; but, more and more have obviously figured out how to avoid "nomorobo".

The best caller blocking service I have found.

Nomorobo has been a blessing in our house where we watch 2 young boys. One ring and gone, no chasing the phone instead of the boys.Only issue is some other Time Warner Customers hear only one ring at their end and assume they lost a connection. The phone in our house keeps on ringing. Regular callers have been informed of this issue and they wait us out.

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 works extremely well. Now and then I report a robo call that was missed.That reporting feature works well also. It's all very good and my family loves the fact that unwanted computer generated calls no longer bother us. Actually it helps cut down the robo calls because apparently many of the robo callers give up calling as time goes by.
