It's wonderful! Want it for cell phone too.

Works great

I have Time Warner Digital Phone and several friends, also TWC Digital Phone subscribers, had a problem calling me. They said my phone would ring once or twice and then hangup. I had to disable Nomorobo. I was very pleased with Nomorobo and would activate again if you could resolve my TWC issue.

I absolutely love it!!!! Being a senior, it's no fun to have to be getting up from your cozy chair or bed to answer the phone unless it's necessary. When you do answer and get silence before some salesman or money raiser picks up, it is extremely annoying. I really do thank you all at NoMoRoBo, and I have been telling everyone I know about it.

so far is doing a good job.

I thought I liked it at first. But soooooo many calls get through! The other day it was 3 in one hour. Why is that??????And almost never get the single ring that signifies a blocked call.

Very pleased with RESULTS ! The larger your data base becomes, the better we like it. One of the more useful applications in our modern lives ! Thanks very much !
