Great product for land lines. Easy set up and reliable results!

Some of the Robo calls that come in do not have caller ID so I cannot block them or even view them. The default display is the number of blocked calls.

This is my fourth call blocker (2 V5000, 1 V10000, and now the V100K). This is easily the best one yet.

I bought the new CPR call blocker V100K to replace my V5000K unit as I needed more blocked-call storage. I entered over 1400 numbers into the new device which worked well for several days until the phone once again began ringing with spam calls. The device showed zero blocked calls in the list. I sent the unit back to the company yesterday and I am waiting for a replacement. The device when working properly still has a serious limitation as it it will not automatically block "Name Unavailable" calls. When it blocks it only does so on the basis of the number.

The call blocker seems to be working, which is a great relief from the many calls I was getting before buying it. Thanks.

My device stop working and they replaced it

This is the third CPR Call Blocker I have purchased. I was told it would block all calls marked "unavailable". However this is not fully truthful. If the call comes in with "unavailable" in the caller ID screen and also shows a phone number, then the call will not be blocked. For this reason I returned the unit for a refund. The main reason I bought it was to block unavailable calls because I have been receiving up to twenty calls a day.

The call blocker has cut down the ammount of calls to almost none.

I can't get call blocker to work with Samsung house phone system. System has multiple lines that I can't figure out how to get blocker to work on home phone number.

love this thing
