DataShark Network Cable Tester - Cable Mapper, Check Continuity - Test Patch Cords or Installed Cable Runs

Tool is as described (continuity checker only, no performance testing), and quickly confirmed some good cables in a new installation, as well as one bad one which had been wired as 568A on one end and 568B on the other. The cable worked fine, though, since the switch was autosensing. Was a little disappointed to see the same unit at Home Depot for less money, even taking tax into account, but its still a lot easier to walk to the mailbox than it is to drive to HD.

This is the go to tune for testing your Internet connections it is simple to use and very accurate

Meter did not work. Wouldnt even test the sample cables provided with the product.
