"I like this better than the other socket tester I got which was a lyvia mains socket tester because it comes with an RCD tester that has proven itself worthwhile with my caravan electrics. That said, the red LED isn't very bright compared to the green LEDs and secondly I had a status of RED GREEN GREEN which isn't even listed on the key so what does it then mean? Also, I put the neutral and earth together from my inverter and it said everything was correct, yet when I tried the RCD tester the RCD didn't trip so I'd be interested in buying the Kewtech socket tester to see if it has the problem, either way I'd buy this again because it is a good price and has some good features and also because Fluke have a good brand reputation.*Update* The second LED has gone, £40 for a tester I can't use, will be contacting Fluke for a refund."

Setting up expensive equipment in a venue, this just gives you a little more confidence that the supply is wired correctly. Careful with that RCD test button, as just an accidental press can result in you running around to find the distribution board to reset the circuit breaker.derek
