Just last week, 8,265 people got Nomorobo protection!

It seems to be working fine.I'm getting just a single ring now and I assume that's a call you've intercepted? Also, are you intercepting calls from WITHIN my state? (California)

We love it! The first few days after we activated it my husband and I were amazed and now most of the calls have stopped. Thank you

GREAT! Tried donotcall registry over and over. What a joke! However, after a few weeks with nomorobo, all of the junk calls stopped dead! Thank you and please keep up the good work.

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.

Nomorobo has saved us for ripping the phone out many times. 5-10 calls a day are stopped in their tracks. Really works.
