CPR Call Blocker USAReviews of callblockerusa.com

So happy you made this product. First week was exceptionally quiet! LOL! Also, door sticker for no door to door sales came in handy just yesterday. Thanks again.

works great

Easy & a great price, just in time our old CPR call blocker was almost full. Thank you

Replacement for one that died. This one works great. This is now my fourth one and hopefully last. Can’t believe that we’ve got over 5,000 numbers blocked. After all, we’re on the do not call list.

Easy to use, it has given our household a break from the constant ringing of the phone. Less than a month and I already have 110 numbers blocked. Easy to connect and instructions are well illustrated.

I bought the CPR Call Blocker because I thought it was the best option on the market for my needs. My phone would ring all day with spam calls, and I needed some relief. After installing it, the house is now so quiet, that my wife and I laugh about it, instead of crying about all the spam calls we were receiving. A few calls get through now and then, but nothing near the amount of calls we had been receiving. Thank you, CPR for coming to our rescue.

This was the very very very best thing I bought. I have peace & quiet & no more interuptions from people I don't know. The BEST thing on the market.

I ordered an upgrade to our old Call Blocker and the new unit is wonderful. With a reduction in the number of annoying phone calls, the household is quiet once again. This product is well worth it; excellent quality and easy to use.
