Winner Mains Polarity Tester Plug

This is a great little piece of kit, well made and looks good, works perfectly and indicates if everything is connected properly and also if any connection is missing. Pure value for money, would definitely recommend it.

Excellent price and a useful gadget to have in the toolbox. Used to test my home sockets and gives some peace of mind that everything is as should be. Good for a quick way of fault finding.

Very good, simple & practical. However, the loss of a star is due to the statement on the back of the packet the plug came in, which states: "The testing covers most common situations except when the Earth and Neutral conductor are reversed". Now I'm no electrician, but I'm guessing that it'd have been nice to know this...

To be honest I was just looking for a light which I could fit in my pocket and plug in to quickly tell me if the socket was still live before working on it. When I found this thing existed at such a price I thought it was a bonus. So far all of my sockets have shown three lights which is good and means everything is as it should be. I trust the device works properly based on the many other positive reviews and the fact that it's quite a simple device when you think about it. For the price and time required, it's got to be worth it to check all your home sockets are safe.

For campervan and motorhomes in the UK the strict electrical standards for hookups are taken for granted that they are reliable and consistent. Abroad, however is not always the case. Hookups can be checked using this device to check and confirm that the supply is correct and safe. It indicates different configurations using a combination of lights, including reverse polarity, live earth etc. All of which could prove extremely dangerous. I intend to wire this into the supply before the main power switch allows it into the campervan providing a simple visual safety check before any power is allowed to pass into the van.

This product has saved me literally hundreds of pounds, now i live in a old house thats not had the latest box installed but it does work. Now, what was happening was a mistery and the power kept tripping and everything would go off, we've had everything unplugged and back again and we just couldn't find it, so we called not one but two electricians both wanted to install a new box so they would be more sure of where the fault was. Okay, now im getting quotes for 550 pounds and they said it might not sort it. The night before i cancelled the electrician and had an idea of trying this plug detector first. I can not tell you how amazed ive been. I asked my daughter to go round the house, which she did and one of my socket only lit up two lights. Husband came home, told him, so next day went out and bought a new plug socket had it installed and we have had not power cuts for 7 days now when we could only go one or two. How amazing is that? For a fiver instead of fivehundred...no brainer! *update* it's now been 8 months and we've still had no problems at all. I am so pleased I haven't had spend all that money on an electrician.

This is such an incredibly useful bit of kit. It turns out that the previous owner of my house wasn't as competent at DIY as he thought. This helped me track down a fault so that I could fix it myself, saving me the outrageous cost of an electrician. It works perfectly, and it's completely foolproof. The display clearly shows you what's wrong using the handy guide stuck to it. Every DIYer should have one, and at this price there's no argument.

Bought these for France this summer but have tried it out in the house, quite small but does the job so bought another two for my sisters who are going to France too. We can all keep them in our vans. Good value for money
