This is Simple, Inexpensive, And Works Great !

Reviewer: from Boston, Ma

I do Cat 5 installs for a living. This is the best I found for quick initial pin/wiring checks ! (Honestly, that is usually good enough). I like the pin-out diagrams on the cover, with some room for small notes too. This tester is quick & simple. Similar Items are around $75.00. For this Price, you can afford to loose or break a few.
