Negative Positive
Title: Area Code Changes
Review: CodeTracker tells me: a) where unknown callers are calling from (using table on back plus caller ID), and b) what time zone callers are situated in (useful when returning messages), and c) it takes the hassle out of splits, overlays, new codes and changes. The table on the back is quick and has all the changes explained clearly, and the maps are useful. Yes, you're right! I like it. I bought a pack and put one on every desk in the office. I reckon I got my money back on time saved within a couple of weeks.
