"Yes it's pricey, but as another review said, you can't put a price on your safety. Check both sides of any flex or cable your going to check which is a good idea when you have a whole bunch clipped together under the floor. Simple to use, reliable and sturdy enough to throw in your toolbag"
"Solid piece, even if it is a bit expensive. Auto shut off is nice as it saves power. It also detects with a sound. Not sure how far it can detect, it pretty much as to be touching. If near the CU it detects that. Only had it a few days so can't comment on reliability."
"I originally bought the cheaper blue one but that lasted about 6 month before it broke. This one is slightly more expensive but has a solid feel about it. Great audible & visual alarm when current detected."
"A must have for every one out there that works with electrical cables.The quality is simply amazing (it has nothing to do with the cheap ones,you can tell from the moment you hold it in your hands) the price is very good & it's Fluke of course which comes with a 2 years manufacturer warranty.It's a must have for all electricians.Would definitely recommend this tool."
"This Fluke AC Tester is simply the Best, I have used so many different makes in the past and none more reliable than the Fluke. If you don't owne one then your risking your life, you need to trust your test tools get the best, don't settle for the rest. Most people coment it is expensive, really,, I supose that depends on how much you value your life BUY THE FLUKE FROM SCREWFIX NOW, DONT WAIT"
"I initially bought the cheap blue voltage tester screwfix sell, as I'm really a DIYer so don't need the best of the best. However upon testing I found the cheap one a bit unreliable with whether or not it would light up!! Which considering that is it's only function is a bit daft.
So I decided I had better spend out and buy the decent one - after all the whole point of this device is to be completely reliable so you don't electrocute yourself. I have to say I've been pleased with the fluke - it has been 100% reliable and that's what you need. Also easy to change the batteries (the cheap blue one I couldn't get the batteries out!).
As pointed out by others it has to be right next to the 'live' wire within the cable so make sure you test against both 'sides' of a cable to ensure it is not live.
A tone (beep) can also be set to activate or not depending on your choice. Although I admit I haven't worked out how to turn it off or on yet (haven't read instructions!). The red light is sufficient in my opinion. It flashes twice per second to let you know it's on, and lights continuously if it detects live.
FYI this cannot function as a live wire detector for cables buried in walls."
"I bought this to identify a supply cable in a tight bunch of cables all with sheathing (lighting circuits, domestic job). It works fine through sheathing and it would flash/bip only when you on the side of the cable with the brown (line) wire. Since than I used it many times in similar situations, never failed me. One of the tools that I have often with me. Bit expensive but overall happy with the purchase"
"got this product on offer, so can't grumble at the price. 1st day I bought it used it six different times. You can easily keep it in your pocket all day so for a heating engineer like me there's no need to keep going to the van for the multi meter. This item is a time saver and would highly recommend."
"This probably saved my colleagues life today. I always have it in my pocket, and so when working on a 400v supply and nobody was sure if the feed to the isolator we were due to be working off was live or not, I produced this from my pocket and determined it was still live. "I think it's off" could have been a costly assumption, certainly more than the £22 price of having this to hand."
