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

Works great. Allowed me to check each run of CAT6 in new construction to make sure they were correctly connected. More importantly, it allowed me to find a cross connect error and fix it. The device only tells you what type of error you have. You still need a VOM to identify the location on the cable run.

Clever handy tool.

As advertised with a great price

Product is accurate. I used it to run my whole house Cat 6 cable.

Avoid this hunk of garbage. Spring for a name brand device with a screen that shows if its passes, has an open, etc. This shows nothing, it hard to understand and is cheaply made.

Cheap, reliable, does the job, what else can you ask for?

Bought one of these at Home Depot. It was DOA -- didnt function at all (aside from the power light).

For the nice low price, this does the job quickly and effectively. Drop your cable in and it will quickly rotate through, checking connectivity on each pin. As I would imagine is the case with all cheaper cable testers, this isnt *entirely* idiot proof, but its close enough.

I wired the lower level of my house with Ethernet cables. This tool made connecting the heads a breeze.

Works as described. Helped me troubleshoot an issue with an Ethernet connection that was daisy chained. Ethernet clearly needs single ended terminations and cannot be daisy chained. Good learning experience for me. Just wished I knew that before I decided to go cheap on the cables and not run a dedicated Ethernet line for every connector. Costs a little more and requires more connections for the bridge, but no other way to get it done right.
