IT REALLY WORKS!! I HAVE THE CPR V5000.
I really appreciated the customer service when I asked them to change my order from one call blocker to another. I followed the instructions and had no problem hooking it up. Before my Call Blocker, I was getting scam calls every 3 HOURS which included the middle of the night and this occurred every day. If they leave don't leave a message that I know is a real call for me, I block them. So far I have only received 5 calls that I had to block since I received my Call Blocker which has been about 8 days.
