"A quick and easily used piece of equipment for the DIY enthusiast . It gives peace of mind after carrying out a relatively simple DIY task . The socket tester performs all the checks on a domestic outlet that I needed . Not certain about its durability as I have only had it for a short time . A good piece of kit but rather costly ."
"Bought this with the initial intention of sorting out a problem at a flat I let out but had a socket at home that worked intermittently that we never really used so tried it on that. It showed up as N-Fault. Took off the wall socket plate (after turning off the power!). Removed N wires and replaced firmly back into contact points, (noticed retaining screw was a little lose when undoing initially). Tightened screw, replaced cover, hey presto 3 green lights - problem solved in a matter of minutes! Highly recommended product"
"As an electrician, this comes out of the toolbox almost everyday, and certainly saves you time while out on jobs. Simply plug in and it will tell you if the polarity is correct. Would def.recommend to any future buyers."
"Every French campsite is different. You need to test for reverse polarity. The Kewtech Kewcheck 103 is ideal. Fast response and you can hear from outside whether there is a fault and then go in and check the LEDs. Would not go camping in France without one."
"Replace old plug in socket tester with this and immediately appreciated the difference - this unit has an audible alarm which is a great help when checking or confirming which circuit the socket is wired from, saving my legs and my sanity."
