Great Features But Buggy Operation…
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.
