"I don't normally write reviews but in this case I almost did not buy this product due to an earlier not so good review. However the brand lured me in and I have found it a great bit of kit. It does not have an end cap but the whole back slides off. So it looks like some earlier reviews are for the wrong product which is somewhat misleading"
"Got this because other brands out of stock, but it seems just the job. Good clear indication when voltage detected, yet not overly sensitive. Could maybe be the better for having a buzzer as well, but on the other hand that's just something else to go wrong. Time will tell on reliability, but it looks reasonably robust, and should last OK if not abused."
"The detector is not sensitive enough to detect current in specific wires in say a switch, only the switch itself. If you have two live & one dead wire in a 3 gang switch, it will show a positive, as there is current in some of the wires. Not very useful."
"I have used this of a number of years and have always found it very useful and reliable. I always try to buy decent tools as I believe you get what you pay for. However the first ever time I dropped this (onto a carpeted floor and not concrete!) the end cap came off and it hasn't worked since. That's the reason I'm not recommending it as I think it should be of a more robust construction."
"Just bought one of these, got it home and tried it against a working socket. No red light came on. I thought that the batteries were flat so changed them for new ones and tried again. Still no red light. I'm going to return this tonight on my way in to work for a refund, and going to buy a different make."
