Kewtech Loopcheck 107 Advanced Plug-In Socket Tester is rated 4.8 out of 5 by 5.
Rated 5 out of 5 by from Loop check 107 This is a really useful addition to my kit. A cut above the average socket tester. Perhaps a little more expensive than a lot of other products, but I don’t personally put a price on quality items. If there is a device to help me do something better then it a must have for me. Lightweight, easy to use and view with bright lights and audiable warnings. Good piece of kit.

Rated 5 out of 5 by from Great quick checker The special feature of this device is the earth loop impedence check - most plug in testers do not have that. However it does not give the value of Ze which a professional electrician would measure - it simply indicates if there is a possible earth fault. In a quick check round 3 properties I have found a possible earthing fault in an outbuilding which now requires further investigation. Well worth the money to be able to check so quickly and easily.

Rated 5 out of 5 by from Worth the money I bought this because my house was over socketed for no and unsafe reason (if that makes sense). On a basic tester it would have shown that the wiring is correct (3 green lights). This however showed on several double sockets that one was good and the other needed to be checked. I called a quilified electrician to have a look at this and they found out there was a broken neutral in the circuit. Once the broken neutral was found and resolved the double socket now shows both are good in the circuit. I tell you something it is worth every penny especially if you want a peace of mind on how sound your electrics are!

Rated 4 out of 5 by from great little item This does a good job. I haven't seen it complain about a faulty outlet (my wiring is just too good! :-) ), so strictly speaking I cannot tell whether it is actually able to detect faults, but I assume it does. Minor disadvantages: - the beeping can be quite annoying. It would be nice if you could switch it off and stare at LEDs instead - there is not even a basic explanation of fault LED patterns on the device itself, unlike on most cheaper ones. So you better keep the manual safe (or look it up online, which is fortunately available). But overall, I think this is a great little device to have.

Rated 5 out of 5 by from Advanced socket tester Quick and easy way of testing all sockets with confidence. RCD check particularly useful. Good for checking other peoples work. A must for electrical safety Well worth the cost considering its features, over other socket testers.
