Just last week, 8,252 people got Nomorobo protection!

I think it's great!

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.

Finally a system that works to block unwanted calls.

Fabulous - Such a great feeling when the phone rings only one ring.

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.

Particularly during the period just prior to the election, Nomorobo was an unbelievable time saver. I was able to concentrate on what I was doing without constantly being interrupted by unwanted calls.

I think its fantastic!
— Carrie C, Nov 29th, 11:21am
I love it! It saves me a lot of aggravation not having to even check the Caller ID. When I hear just one ring, I know it's no one I want to talk to.
