MX AC Line Fault Detector Plug Tester – Electrical Socket Tester for Wiring Issues – Detects Live Neutral & Earth Faults – LED Indicator – No Batteries Needed – Compact Design (Black) : desertcart.in: Industrial & Scientific

Review: Absolutely zd - Absolutely super product, those who leave negative reviews dont know how to use it. The built is sturdy very much and fits imto socks snugly well. One guy had left review doesnt even fit into 5a socket thats because 5a is non standard socket, most sockets r 6a not 5a. And those who say multiple lights are on, that indicates multiple faults. Those who say loght turns on even when off..try turning the switch on, it will show live and neutral reversed, which wud make the current flow even when switch is off, hence it lights up When the light is dimly appearing means fault is there (like earth fault) but is more minor. Its dead accurate in my opinion and has saved my appliances many times, and my family from shocks. Highly recommended, also can be easily used by electricians and people who are less experienced with complex multimeters for fault detection as its simple 3 led and written aout it right there no complex screens. This device is dead accurate, if u think its wrong or faulty then first check your wirings.
Review: Tester Pin size is too small - Tester Pin not properly fit in socket, size is too small, work good, easy to understand, quality is good but pin size is small so hard press for fix it into socket.
