The call blocker has done what it said it would do, block unwanted calls. I am no longer bothered by the nuisance calls i use to get on a daily basis.Any numbers not loaded in call blocker can be added very easily by you. I recommend this product.

Immediately reduced the number of calls we get. The robo marketers are smart though, changing numbers quickly. It’s easy to block calls though as they come in, so they only get one shot. Good job call blocker!

This is my second CPR Call Blocker device. I love it! I guess this is an upgrade, of sorts, to my 5 year old device. So far, it continues to be a good decision.

This is a good product. It does what it was meant to do. I noticed a reduction of spam calls after I installed it.
