I love nomorobo, it had made my life so much easier not having to deal with people you do not want to hear from. Thank you very much.

It's great! Let the phone ring once. If it rings again, it's real. In not, we say, "Gee, Thanks, NOMOMOBO!

Its great!! More than 80% of our phone calls are handled by Nomorobo quickly & efficiently. We have recommended it to everyone we know to end unwanted phone calls.

Incredible. We smile, knowingly, when the phone rings ONCE (and one time, only) and the readout displays "Unknown Caller" or 800-***-****. Keep the server room nice and cool, 'cause "revenge is a dish best served cold..." :-)

Works great! Wouldn't be without.

Love it. I usually only hear one ring and then it cuts off. I know that Nomorobo has activated and stopped the robo call.

Very happy with it. Works well.

We think you are terrific...it works really well! Amazing how many calls there are..we just wait for 1 or 2 rings and they go away.. Thank you so much!
