It really works! I have a handicap husband so I still need a landline as a backup for my cell. Nomorobo stops over 75% of calls on our landline with that "one ring", Thanks.

It is AMAZING how many "one ringers" we get! So glad we have Nomorobo and have installed it on our parents' phones and recommended it to many others! Thanks!!!!

Has made my entire day more enjoyable, especially dinner time.

Great Program!

THE BEST !!!!!! It shut down the regulars immediately. The new ones....one call and down the go. A true knock punch.

Absolutely love it. The best thing since the telephone.

It works! It's stopping about 8 calls a day. We love it.

I recommended it to a few relatives over Thanksgiving weekend. I am grateful to have Nomorobo to prevent so many annoying calls from coming thru! It took a while to get it installed on TWC, then another time period till I got any calls to screen. So glad I persevered with the help of Betty Lin-Fisher of Akron Beacon Journal. Some of my calls are stopped after 2 rings, rather than one - but that's great! I seldom get robo calls, but still report when I do. Thank you for coming up with this.
