Had it for a about a year now. We Love it. Phone rings once and thats it!! Then We both yell, "ROBO" and laugh!😊

The best service ever!! One rings means a robo call blocked. It makes me smile. Wish I could get the same service on my cell phone.

I think it's the best thing since 'sliced bread'. My spouse and I look at each other and laugh when we hear that one ring. Another marketer left high and dry! A great help in this age of intrusion.

This is a great system that catches all the robo calls I receive. Great job, I figure another year and the robo scammers will be off my line. Keep up this great system and stay ahead of the scammers. Many, many many thanks

It WORKS!!!!!!! I have been telling EVERYONE I know about this service. I went from an average of 3 or 4 annoying calls every day to about 1 each week. Peace and quiet during dinner.......priceless.
