It has reduced unwanted calls significantly. I have already told friends about it. Now if only it could block calls with caller IDs of Blocked or Anonymous that would be the icing on the cake. We never accept those calls.

This is a great service. All those dinner calls that are robo calls to sell something are now just one ring and do not disturb us. We now wait for at least two rings before we answer any call to see if was intercepted. Thank you very much for a GREAT service

Great! We love to hear the 'no-mo-robo' sound of one, single ring. It makes us smile all over. If a call is not a nomorobo call, we wait until just after the third ring, picking up the receiver just before the fourth ring. Any unwanted callers usually hang up before the fourth ring. Makes life much better.Love it. Have mentioned it to countless people. Some of them however, can't seem to get it due to their provider (Xfinity I believe.) Hope that changes in the future. Will try the Beta as soon as possible.EDC

Aaron foss is a genius. His Nomorobo technology continues to function above our expectations monitoring our home land line system, running interference against even the most persistent robo marketing calls! I cannot help but smirk when our phone simply emits the single ring, alerting us that yet another robo call has been blocked; hoorayyy for Mr. Foss. Our life is much less stressful knowing that Mr. Foss's electronic "secretary" is fielding unwanted incoming calls, especially those around dinner time. Thank you Aaron for all of your hard research and work to bring nomorobo to life!

Nomorobo has saved us for ripping the phone out many times. 5-10 calls a day are stopped in their tracks. Really works.

One of the outstanding products of the century! Even more useful than the invention of the phones it blocks!
