1. I opened this email. My privacy was immediately violated. Cookies were placed on my system. It denied me an opportunity to adjust to anything near my preference. I do prefer that NO COOKIES OR ANY METHOD BE USED TO MONITOR MY SYSTEM. This is why I PURCHASED this unit.....PRIVACY!!!!

Thank you for your feedback. We completely understand your concerns about privacy. It appears your experience relates to Trustpilot's review invitation rather than the CPR Call Blocker itself. We hope you're enjoying your call blocker and the peace of mind it brings!

Impossible To Return Items - Phone Numbers/Links Don't Work
They provide no return service for products. You can only communicate with an AI chat agent that seems to go out of it's way to waste our time, and not address our concerns.
If you go to their website, NONE of the phone links/forum links work. It has the feeling of a giant scam operated from overseas.
So now I'm out almost $100 because this company won't even communicate with me about setting up a return. I would LOVE to take these people to small claims court and sue them, if it wouldn't be such a waste of my time.
So if you buy something from these people, you better like it, because you can never return it.

This doesn't cut down on calls at all
This doesn't cut down on calls at all. Also no one has returned my email that I sent for a refund.

Unimpressive customer service
It took five months before my email was answered which took at least two more emails. When I was finally offered a replacement at a discount as the warranty had finally ran its course, it was then cancelled because there were none in stock. Not impressed with the customer service. I had issues for at least 6 months and after checking everything else, it took a while to figure out that it was the product that was causing the issue then my original email was not answered.

Hello Bonnie ... Thank you for taking the time to share your experience. We apologize for the delay in responding to your original enquiry and understand how frustrating that must have been, especially while you were trying to determine the cause of the issue.
After reviewing your case, it appears the call blocker was originally purchased in 2023 and the reported problem involved your mother's number being blocked. In many cases, this can be resolved by unblocking the number directly on the unit using the following dial-tone code, which is also included in the user guide:
**6# (wait for beep) [enter number to unblock]# (wait for beep)
As the device was outside its warranty period, we offered a discounted upgrade to a newer model. Unfortunately, there were difficulties processing shipment to Canada from our US warehouse. While shipping to Canada is possible, it can sometimes be costly and take considerably longer than domestic deliveries.
We appreciate that this situation did not meet your expectations. If you would still like to discuss a replacement device, please contact our support team again and we will do our best to explore the available options. Alternatively, we recommend trying the unblock procedure above if you have not already done so.
Thank you for your feedback, as it helps us improve both our support and communication processes.

The device has not blocked any…
The device has not blocked any marketing calls. Appears a total waste of $!!
Response from CPR Call Blocker USAMay 14, 2026
Our Call Blocker is designed to actively reduce nuisance and marketing calls for thousands of users, with performance improving based on how it is used.
For best results, Caller ID should be enabled so the device can accurately identify incoming calls. Using the red “BLOCK NOW” button helps the system quickly learn and strengthen future blocking. Additional control is available through programmable codes, including the option to block entire area codes for more targeted protection.
With the right configuration, the device becomes increasingly effective at stopping unwanted calls. Give us a call or email and we can help you get the best out of it.

The product does not work properly
The product does not work properly. It seizes my phone line and prevents incoming and outgoing calls. I requested information to return 17 days ago. I have emailed and called with no response. I chatted with a representative 4 days ago and she diagnosed the problem. She created a ticket for the support team and "elevated the issue in their queue." I still have not been contacted for resolution. Do not buy from this company.

Hi, thanks for your feedback and we’re very sorry for the trouble you’ve experienced.
This is not the service we aim to provide, especially with the delays and phone line issues you’ve described. We understand how frustrating this must be.
Please contact our support team with your ticket number so we can urgently review and resolve this for you.

Spammers are using random or local numbers
Spammers are using random or local numbers so blocking by number stops that specific number, but not the next fake one. Even prefixes are always different. So I always have to observe caller id and hit Block button. Rather useless for me.
Response from CPR Call Blocker USAMar 9, 2026
Hi Ken, thanks for the honest feedback!
You're spot on. Spoofed local/random numbers make single-number blocking tricky, and having to manually hit Block each time can feel frustrating.
The good news is the big red "Block Now" button makes it super quick, and the device already auto-blocks thousands of known scam numbers right out of the box. As you block the sneaky ones, your personal list grows, and most users see a big drop in calls (often 60-90%) within a week or two.
Our models also let you block entire prefixes or area codes to knock out batches at once.
Thanks for sticking with it. We're all fighting the spam together! If you need tips, we're here.

Hello Victor, We completely understand how frustrating it can be not to receive an order. Unfortunately, we’re currently unable to ship the CPR V100K Call Blocker to your address in Mexico. When your order was reviewed, you should have received a notification explaining the situation at the time the refund was initiated.
The good news is that your refund has already been processed, and you should see it reflected in your bank account. If you don’t see it yet, please check with your bank, as processing times can vary slightly.
Kind regards,
CPR Team
