I could not be happier with this new CPR Call Blocker USA for my landline phone. I received this Call Blocker in only a few days after ordering it. I am amazed at how quickly the nuisance calls are blocked the minute I hit the red button. It is a delight that I have a means of fighting back these unwanted calls. I highly recommend this CPR Call Blocker USA for anyone who is fed up with nuisance and harassing phone calls and is willing to try it. I have had it about a week now and already have 27 unwanted callers blocked!
