Thanks so much for the lovely review! We're so pleased that the CPR Call Blocker is doing its job and keeping those pesky calls at bay. Wishing you many peaceful evenings free from nuisance calls, and if you ever need us, we’re only an email away.
We're absolutely thrilled that you found the CPR Call Blocker so simple and easy to use – that's exactly what we set out to achieve! No complicated menus, no tech degree required… just peace and quiet from those pesky calls. We really appreciate you taking the time to share – it made our day!
My experience was not so great. The black cable was missing, and I notified the company repeatedly of this fact, but to date the request has been ignored. This request now has been over a month!
Thank you for taking the time to share your experience. We’d really love to put this right for you. Please send us a quick message with your order details (or email our support team directly), and we’ll make sure a replacement cable is on its way to you. Thanks for your patience.
Unfortunately, your product doesn't work with Magic Jack, but your support reps are top Notch. They went above and beyond to help me. So much so, I'm very sorry that your product doesn't work. I shall miss them so very much!
Thank you so much for your kind words. We’re sorry the CPR Call Blocker isn’t compatible with Magic Jack, but we’re so glad our support team could help. If your setup ever changes, we’d love to welcome you back!
well, I asked twice the support if this thing works here in Canada..I've got it yesterday, I'll try it tomorrow, a throw of the dice, I'll see..
Thanks so much for giving us a try - and for your patience while checking things out with support! If you need any help getting set up, or have questions once it’s running in Canada, we’re always here and happy to help. We hope it makes your landline a whole lot quieter.
I was blown away at how quickly CPR Blocker was able to block unwanted calls.
We’re thrilled to hear your CPR Call Blocker got to work so quickly - peace and quiet restored! Thanks for sharing your experience.
What an AWESOME product! I ordered your V5000 model several years ago (from either QVC or HSN), and we’re still using it today. I recently purchased your V100K model for my elderly father-in-law in Michigan to help cut down on the amount of spam calls he receives. I can’t wait to see how much aggression this is going to be SAVING him! Thanks again for your WONDERFUL product! I guess this means we’re going to have to purchase your latest model now! 🤗 D.B.
Thank you so much for the fantastic review. We’re thrilled your V5000 is still going strong and that the V100K is helping bring your father-in-law some well-deserved peace from spam calls. It means a lot that you’ve chosen us again. Thanks for being part of the CPR Call Blocker family.
I get numerous robot calls a day and this makes it easy to block them. I love it, I don't have to hear my phone ring back to back all day.
Thank you so much for your lovely review. We’re thrilled to hear your CPR Call Blocker is keeping those pesky robot calls away and bringing some peace and quiet back to your day. Thanks for sharing your experience!
I am a long time user of CallBlocker who is very happy with it.
Thank you so much for your kind words, and for being such a loyal Call Blocker user! We’re absolutely delighted to hear it’s been keeping those nuisance calls at bay.
While most nuisance calls get stopped, the occasional one can still sneak through. That's why we have the Big Red Button to manually stop persistant callers. If you’d like a hand fine-tuning your settings, our team is always happy to help.
I’m very disappointed I guess I must have misread what this call blocker supposed to do, but it is very annoying. Getting phone calls one after another in a day and my mama answers the phone still, I guess I thought that the phone would not ring as much as it because they were automatically getting blocked.
Thanks so much for sharing your experience. Our CPR Call Blocker works hard behind the scenes to stop known nuisance callers, but a few may sneak through until they’re added to the block list, a bit like training it who’s not welcome. Once those numbers are blocked, the ringing should settle right down. If you’d like a hand getting everything set up just right, we’re always happy to help!
Disconnected phone cable line from wall outlet and connected it to the LINE port in the Call blocker port. Then disconnected cable from the phone to the TEL port. Now can see display on the blocker screen. When phone comes in I select SPEAKER button on the phone base and then push BLOCK NOW. It seems to work OK, but NOT all the time. NOT sure why. When clocked SUCCESSFULL message and count goes up.
Thanks for sharing your experience. If it doesn’t catch every call, it can sometimes come down to timing or the type of incoming call, but it sounds like you’re using it exactly right. If you’d ever like a quick tip or two to make blocking even more consistent, our support team is always happy to help.
Junk. 99% of robocalls get through. It doesn't screen incoming calls and you will have even more because of this.
We promise our Call Blocker is meant to keep the peace. It usually works best with a quick setup check, so our support team would love to help fine-tune things and get it working the way it should. We’re confident we can turn that 99% around!
The installation was very simple and worked perfectly.
Thank you so much for the lovely feedback. We’re delighted to hear installation was simple and everything worked perfectly - that’s exactly what we aim for. Enjoy the peace and quiet!
I have emailed support and called customer support to find out how to properly return the product . Neither have responded. I'm' mailing it back to headquarters.
the person we talked to about replacing our not working call blocker was very pleasant and friendly and knowledgeable. the units we have received through the years are very easy to set up and operate.
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!
Always blocks what I want blocked, finally starting to get a lot less calls.
Not satisfied with this CPR Call Blocker USA. I want to return this item and get my money back!! Very disappointed indeed!! I would like to have my money refunded as soon as possible!! Thanks, Phillip J. Northrop 23 Covington Terrace Newnan, Georgia 30263
I like the very large built-in blocked phone number list and also the very large capacity for user-added numbers. It is also great to be able to block numbers by area code or by prefixs within an area code. What I do not like is the poor manufacturing quality of this latest version.(V100K). The display often freezes rendering the box inoperable until the phone line is disconnected and reconnected. I previously returned another unit of the same model as it unacceptably erased on its own all of the hundreds of blocked numbers I had entered. Previous versions were much more reliable but have much smaller number capacities.
