Klein Tools VDV526-100 Network LAN Cable Tester, VDV Tester, LAN Explorer with Remote

I used it to test RJ11 telephone plugs, and RJ45 ethernet plugs. The tester did find faults before using the defective cables and losing time to do trouble shooting. Its worth the money.

Good value

Great ethernet cable tester and also very accurate.

I was impressed by the quality, ease of use and versatility of this tool.

Works as advertised. Found crossed wires on first use, saves time by testing wiring before connecting to equipment

Dont know how I survived all this time without this. Makes networking a system a breeze

I have only used this once but found it worked fine on a properly wired cable. I like the idea of the remote capability which allows for easy determination of a connected cable without having to have both ends in the same place or having to watch led sequences. I do feel that the unit is a little over priced but Im glad I got it.

This one is very reliable and simple. Well made.

Struggled with making quality home LAN cables for years, bought this tool which auto checks and diagnosis cables. Cable ends I though we perfect showed a defect and when correctly led work much better. Should have bought this years ago

This tool helped me find a shorted CAT 5 cable within minutes. Easy to use and did what I needed it to. Very handy to keep around.
