Greatest thing since sliced bread! Every time we hear 'one ring' we high five each other and break out in a big smile. Thank you.....thank you.

Great service, and I'm enjoying a good chunk of those 70,000 calls you block every day. The only improvement I can recommend is some way to mute the single ring that you're unable to stop. Guests sometimes ask why our phone rings only once, which does give us the opportunity to explain your service. Keep up the good work.

I am still getting some robo calls, why?

Not only does the service work nearly flawlessly - no false positives I've been told about - but also it's simple to work with their helpful people to research and add new numbers that should be blocked. I'd be completely happy to pay for the service to make sure it stays online, yet they refused when I offered. Amazing.

I used to get at least 10 calls a day. Drove me batty. Now, with Nomorobo, i get a single ring once or twice a day. Thanks a million!
