Just last week, 8,269 people got Nomorobo protection!

I think it was really, really great during this past political season....

I think it is great! Love that it only rings once and then I know it was picked up by Nomorobo and that I can relax and not even look at the caller ID.

Overall good service. Would be better if four-digit Caller ID numbers could be blocked. Would be much better if the phone didn't ring at all on a blocked caller, instead of allowing one ring.

Unbelievably good on phone service providers that accommodate this application.

It gets almost every call. Terrific, and well worth triple the cost.

I was at first skeptical, but after a few calls, I was convinced, this thing works! We see the call show up, on our caller ID, it rings once and it's gone! Simply Amazing! I have recommended it to all of my friends.

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