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.

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.
