Thank you for this service. I get a lot less annoying calls.

It's great we have very few calls than get by the system.

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 LOVE it! it has made a huge difference in the amount of calls that are unwanted. thank you aaron!

Love it! The annoying solicitation calls have ended!! Peace and quiet have ensued.

One of the outstanding products of the century! Even more useful than the invention of the phones it blocks!

An Excellent Product! It would be even better if the single ring were eliminated. That would be the best for total isolation from the annoying robot dialers.

My father passed away leaving my mother alone. The phone, which in her day was a GOOD thing because it meant someone wanted to talk to you, became an enemy. The number of scammers harassing her was mind blowing! With Nomorobo, her phone is again now a source of comfort. Thank you, Nomorobo!
