a great service to escape irritating calls

Love it, it stops about 10 calls a day. Saved us from just cancelling our home phone which is still considered.

It is worthless. We are constantly getting robotic calls.

I can't believe how effective it is. Thank you for providing this outstanding service at no charge.

Its....grrrreat!

Nomorobo is fairly effective. However, it has caused us other problems with those calling our Time Warner phones from their Time Warner phones. Therefore, we have disconnected Nomorobo and our Time Warner is back yo normal but the robo calls have increased. I will be happy to reconnect when you can better interface with Time Warner.

I think that this is terrific. It has eliminated about 90% of the calls to the house. The other 10% we do not answer if we do not recognize the calling number. Thank you.

Want it to stop the dreaded "1" call. That is all that appears on my caller ID, ATT cannot stop it. HELP
