ProsKit MT-7058 Wire Tester Mini Lan Ethernet Cable Tester Multifunctional Network Cable Tester RJ45 RJ11 RJ12 Cat5 Cat6

Also no A23 battery included in mine - thanks to the other comments I remembered to order one at the same time.
It feels cheap and plastic-y but so will anything else around these price points. The nice thing about this budget tester is that as well as leds for each wire, it also has a few diagnostic leds - so after testing it will indicate if the cable is Straight/Crossover/Shorted.
If I were you I'd buy two batteries - the resting voltage of my 'new' battery has already dropped a good amount just from playing around with it this afternoon.

If I were you I'd buy two batteries - the resting voltage of my 'new' battery has already dropped a good amount just from playing around with it this afternoon. For occasional troubleshooting this shouldn't be a problem - but if you're intending to test a whole load of cables I'd definitely have a spare handy.
I like it but only 4 stars due to the battery type. I'm much more likely to have a spare 9V lying around - then again I suppose this is a 'mini' cable tester.

Good inexpensive device suitable for any network or it enthusiast. Comes with 12v battery and detachable module for testing long cat5 runs or through patch bays. Picks up wiring errors or damage and can identify cross over cables. Can also test video cables and waylines (bnc analogue or SDI digital). Added bonus is a non contact Ac detector for live wiring.

Don't be fooled by the 12V AE23 battery listed on the 'Features' tab - this is shipped without it.
Just an empty blister where it should be in the packet (we thought it had fallen out). Apart from that it works as advertised - useful if you're making up a bunch of custom length cables, or chasing a fault.

Working well. It was a great help when I first set up the network of the office. Working well. It was a great help when I first set up the network of the office.

I was quickly able to tell which connections in my house were shorted and causing my slow speeds. Tested all my
cables too! I was quickly able to tell which connections in my house were shorted and causing my slow speeds. Tested all my

I needed a tool to test the connection where my LAN was lost and not connected. Great tool and great price. For me it does the trick I needed a tool to test the connection where my LAN was lost and not connected. Great tool and great price. For me it does the trick

Looked at a number of similar units and walked away due to cost. Happened to run across this one and the price seemed reasonable. It has worked a treat for anyone making their own cables it is a must. Saved me a lot of hassle if connectors were not on correctly. A few seconds of testing with this will save you hours of debugging network problems. Looked at a number of similar units and walked away due to cost.
