ProsterNetwork Cable Tester with POE Function - Ethernet Tester Ethernet Line Finder Continuity Battery Voltage Polarity Check Test Multi-Function Cable Tester with Storage Bag

I bought this as I had to trace cables for a line of offices in a business center. Considering the RJ45 cabling looked like it had been woven together by a large spider at various junctions and was behind trunking, false ceiling there was little hope of getting a map of the cables fast. I thought i'd take a chance on the Proster Cable Tester as it was relatively cheap and I didn't want to fork out over £300+ for the more well known brands. I have to say, I was pretty impressed that this one actually picked up every cable run I checked and had the whole lot repatched in no time. It is reasonably accuruate and sometimes needs for you to use rotate the probe or change the sensistivity slightly. But overall a purchase I am happy to add to my list of tools!

I purchased this to replace a failed tester, which packed up after being connected to a POE socket.This one was cheaper. It has a number of tests but none of them seam to make sense when trying to select them.You are not able to identify crossed cables with this. The display just says 1-1 2-2 3-3 etc… even if someone miss wires the socket.The other side flashes lights on the probe. This is adequate but you’ll need to identify crossed cables using the light sequence.It does the job, but I wish I’d purchased the one I had before.

I’ve bought many of Ethernet testers over the past few years, this one is absolutely tat.Ridiculously poor quality. Poor tone and probe.Not even the battery cover clicks on correctly.How this is got good reviews is beyond me.
