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

Best thing that ever happened since the call center came into being. We see at least 5 or 6 calls a day, sometimes more, that are blocked by Nomorobo. THANKS!!!

Love Nomorobo! When the phone rings these days, I don't jump at the first ring like I used to. I wait to see if the call is zapped before letting it interrupt me or waste my time.

Nomorobo is a first class service and very easy to use. I recommend it to all my friends.

It rocks! Saves us from so many calls.On the wishlist, each user could have a personal block list so that they could add numbers to the block list! I'd pay for that.

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.

It works extremely well. Now and then I report a robo call that was missed.That reporting feature works well also. It's all very good and my family loves the fact that unwanted computer generated calls no longer bother us. Actually it helps cut down the robo calls because apparently many of the robo callers give up calling as time goes by.

I find it aborts calls after 4 rings but doesn't block them. I still get many unwanted calls.
