Just last week, 8,273 people got Nomorobo protection!

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

It's the best.....so many calls with only one ring and then GONE!!!

My husband and I love Nomorobo. We were so tired of answering calls and no one was there or if we were lucky enough to be the first to answer, we really didn't want the call.Due to having MS getting to the phone can be hard at times.Thank you!!!!

It's wonderful. Thank you for stopping those very annoying calls. They were never ending and now peace again.

We love it but are now getting strange calls with a 2 digit area code so that they are essentially getting around the nomorobo blocking.
— Brian C, Nov 29th, 10:17am
The best caller blocking service I have found.
