Just last week, 8,280 people got Nomorobo protection!

Best thing since the invention of the telephone

Even when an occasional robo call gets through, I really get satisfaction in reporting that number. Most times, however, after 1 ring these calls go away! I'm loving this...couldn't be more pleased!

My wife and I are finally getting control of our phone back. We love the peace and quiet that NOMOROBO has achieved for us. Thank You a hundred times.

I think it has helped, but quite a few numbers (including Gallup) get through with a single ring, which is less annoying than talking to them, but very annoying, nonetheless because these callers tend to call every day. I suspect this has something to do with the fact that I use Vonage SimulRing to call my home and cell at the same time, but I'm not sure. I've learned that reporting a problem has no effect (but, heck, you're offering a free service, so ...), which I why I didn't bother.Of course, the 2014 political campaign season was still unbearable, and I don't look forward to 2016, but I think your service is a great help, and I appreciate it.

Great service, cut down my nuisance calls tremendously (except that know my captain no longer calls and I don't win anymore free trips, lol)
