## Customer Reviews

### ⭐⭐⭐⭐⭐ Nice tester for wiring testing
*by P***A on 7 March 2025*

Nice product

### ⭐⭐⭐⭐ Accurate fault detector for the price.
*by S***A on 22 September 2023*

WARNING: ELECTRICITY IS FATAL AND CAN KILL YOU. TAKE APPROPRIATE PRECAUTION BEFORE ATTEMPTING REPAIRS ON ELECTRONIC PRODUCTS.The MX 1177 works quite well, it's a small form factor voltage detector with three pins, and it works on most standard switchboards without problems. The front has three LEDs which glow accordingly to the status of the wiring in the switchboard. I've seen some reviews that mentioned that all the LEDs glow regardless of the status of the connection, but that's not true in my case. The lights glow appropriately and I've been able to figure out that three switchboards in my house were wired incorrectly (power and neutral wires inverted). I opened the switchboards and sure enough, each of the switchboards had inverted power and neutral wires.The only problem with the unit itself is that it's a bit difficult to fit into all kinds of switchboards as the pins are spaced wider than usual (by approximately .2-.4mm) which can make some switchboards feel a bit dangerous to plug into. A little bit of fiddling and the plug will fit but please be careful as to not use too much force as the chassis of the plug or switchboard plate may get damaged.This is an easy recommend, does the job and is cheap. 4 stars because I've purchased it recently, the fifth can only be given to things that last longer than 6 months!
