U love Nomorobo. It has saved me a lot of frustration!!

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

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

Good, but still too many calls come thru to my home phone. And during election season its overwhelming. You have to tighten up/expand your blocking filters.

Nomorobo works fantastic, I was getting 13 to 18 robocalls every day. Now we get 0, even blocks the annoying political call. I have recommended it to ALL my friends and family.Bobby

I LOVE it. Everytime a call gets blocked, I say, "thank you, thank you!" We were really targeted by robo calls. This has saved my sanity. Thank you, again.

Love it! Love it! LOVE IT!!! I have recommended it to all my friends. My only "complaint" is that some of them have odd phone companies that don't support Nomorobo. On cell phones? Great! Can't wait; some family and friends have only cell.

I echo others comments. Received 14 calls of which 12 were in November. Thanks Nomorobo.
