Nomorobo is great! I never realized how many of these robocalls I got until I was home all day for a couple of days, Within those two days I received 6 calls. Four of those calls were in one day. It was then that I decided to get Nomorobo. The system picks up the call and your phone only rings once. The call is then cut off. It's a great technology. If you are annoyed by robocalls this free service is the way to go.

I think Nomorobo is wonderful!! It has drastically cut down on robo calls and adding new numbers is easy. It will be great when it can be used on cell phones.

The "greatest Ever". Now if you could get rid of the political calls than it would make it even more great especially since we have another big election coming up!!!!!! Thank You
