It has several nice new features including the ability to store 1000 blocked numbers

No doubt its best feature is that it blocks all "out-of-area" and anonymous (private caller) calls immediately, BY DEFAULT

The unit is feature filled and very flexible

Of all the call blockers I researched this one has the best features and most flexibility

The box looks simple when you judge it by its appearance but because you program most functions from your phone handset it has a huge set of hidden powerful features

Love the feature of blocking a call on the second ring, rather that having to wait until the call ends to block.

I like that the Pro Series has some useful features that are absent on previous models

That is an awesome feature

Amazing box, very powerful features that none of the other have

A great feature is the do not block list to which we added the phone numbers of friends and family that we never want blocked for any

The problem with Code 76 is that it defeats the very feature that blocks most spam calls

One of the best features is the ability to block entire area codes and/or exchanges

The first ring is suppressed on any phone connected to the device, so that the phone never rings for blocked callers--a great feature for the bedroom.

I didn't automatically block area codes, caller names, etc or use any other feature like After Hours mode.

This model and the previous ones have one important feature that the competitors don't have

But we intelligent consumers can sniff out a useless feature from anywhere.

Tech support recommended entering code 76 to disable this feature

The number of available features might be daunting for some people

There is a ton of information but not a good search feature, the FAQ is just a list of issues and solutions listed in order of appearance or something.

It works just as it says

Works as it should.

I had to refer to the instruction booklet for proper way to delete a number from the call history without deleting the whole call history, as well as how to add a number to the VIP list.

Most were out of area, no more, I'm from windows, ÌRS, eçt.. love it.
