I think you are helping me daily - there are so many one-ring calls. Of course, some calls do get through. And there's nothing you can do about politicians. The calls that get through are for medical alerts.

Terrific product. Thank you so much. I tell all my friends about it.

It is great! Thank you soooo much. Some days 5 or 6 calls are blocked. And blocking the one digit number was amazing! Thank you for peace and quiet.

I love it! The only problem is that now I answer calls I would have once screened and ignored since I want to identify and report as many robocall numbers as possible!

This works great, 1 ring & gone,TOO bad it can't stop the Political & Charities, I give to whom I want to, not to callers.

I can't believe how effective it is. Thank you for providing this outstanding service at no charge.

Where have you been all of my life? Thank you.
