I frigging love it. Works well- too bad it can't block political telemarketing

wicked awesome

Since about 80% of my phone calls on my land-line are from unwanted sources, Nomorobo is a wonderful service. It, at least, eliminates 40 - 50% of my unwanted calls. Thank you

AWESOME!Best thing ever from Mount Sinai (like us)! Good luck with making it ever better, e.g. (pipedream?!) a code that I could enter on the phone to automatically report a robo caller to your database. GOOD JOB!

One of the best anti incoming unwanted phone call programs I have ran into. Thanks for what you do,

Thank you for being there!

Love You, Nomorobo!

Great service, but still to many other calls get through. Keep up the great work!!!!!
