"Given the low price of this tester i was very skeptical. However, glad to report that it works really well. It helped me find a couple of cabling faults within minutes. The construction seems fairly cheap so i'm not sure how long it will last, but certainly for intermittent use its well worth a adding to your toolbox."
"As other purchasers have found, this tester does not switch off. Simple fix, remove the front cover (4 screws at the back) reveals the switch is square in an elongated round slot. Use a small file and round the switch on one side and hey presto, it switches off - problem solved! Apart from this the tester works very well and identifies incorrect wiring in a jiffy. Fine for DIY network cabling, probably not suitable for every day pro. use as its rather light weight. I was going to return this, however after the fix and use, its worth keeping for the next networking job."
"Cheap plastic wasn't expecting much. It did work ok and found a mis-wired cable. The on/off switch didn't work and the only way was to disconnect the battery. Believe it or not that was easier said than done, connection was so tight on one pole that the battery terminal broke off, the first time I've ever seen that (top brand gold battery). This product does do the job, yes it's a little slow. Suggest that you check this product works ok whilst still at the trade counter, if it does it's cheap enough, if not get it swapped."
