CPR Call Blocker USAReviews of callblockerusa.com

This is my 3rd call blocker (upgraded V10000). It's really important to block unwanted callers as quickly as possible and clean up the call list every day otherwise you will get buried in all the phone #'s and it can become overwhelming. You need to delete the #'s after blocking and also delete from call list #'s that you don't want to block. Tech. service was very helpful in helping me to block an area code. There are no instructions for that in the user guide.

Our phone is now almost silent since we got our new call blocker. We are not getting those annoying robo calls or telemarketers any more. Thank you CPR Call Bocker.

Works Great!

The CPR unit that I received works great. I like how easy it is to use. Since after I received the new unit, I have very minimum scam call.

Since I hooked up the new call blocker, I haven't had a single call except from people on my caller ID list. I'd been having at least 10 "spam risk" calls a day so this is absolutely wonderful!

The CPR blocker arrived in good time, days not weeks. It does what is advertised, no nuisance calls.

CPR Call blocker is awesome. Have been getting nuisance calls for years. FINALLY SOME RELEIG . Thank Your for inventing this.

It was a snap to set up, and it seems to have reduced - but not eliminated - unwanted calls. We still get a few calls from "City, State" every day. One issue has arisen in that after we #2 a call, that same number rings again within 1-3 minutes. It only rings once, but that's irritating.
