(720) 666-6380 is a Robocall

Works great!! After using it on my line I placed it on my 86 year old fathers phone and if the phone only rings once (which happens often) he knows its a telemarketer

I love it. We get so many fake phonecalls, and while working from home, it interferes with my work day. Now, it's just one ring, and back to peace and quiet! Thank you!

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

I an on the do not call list, but it hasn't stopped the robos. Why don't you turn these people in to the do not call list and reap the fines for yourself??? If you need my permission, you have it.

This is the greatest invention. We have had many "one ring" calls since we signed up for nomorobo and it even keep annoying political callers from getting through (we could see who was calling on our Caller ID ). We hope to be able to add our cell phone numbers as soon as nomorobo gives the heads up on that. Thank you so much! We have already given out the web site to several family and friends. And they have been grateful too.

Love it. it needs to block unavailble call listings as well.

Hey, what is that sound? Silence; life is good again without all those annoying calls ringing on my phone.

It gets most of the robocalls. For some reason cannot stop "unknown name " & "unavailable" phone number. And considering how the robocall industry is evolving, one would hope that Nomorobo keep up.
