Best invention since caller ID!

Every time the phone rings once and stops, we smile and say, "Nomorobo!"

This is the best thing to happen to phone communications. One ring and they're gone. Some still get through but only abut 10%. I'd say that is good work. You guys are the greatest. We can now eat dinner without trying to tolerate telemarketers - even non-profits.Thanks!

It works at least 90% of the time. We get hammered daily by scammers who lie with their displayed Caller ID so this is heaven sent! It's not perfect, but nearly so and the best thing we've found.

It is wonderful. To hear one ring and then silence makes me feel like I won. Some have now had to resort to boiler rooms but it now hirs their bottom line an frequenc.

Nomorobo definitely better than "do not call list".

GREAT! I just wait for the 2nd ring to know if it's someone I WANT to talk to !!
