ULTRICSVoltage Tester, 12V-1000V Non-Contact AC Voltage Detector Pen, Adjustable Sensitivity Electric Tester with LED Flashlight, Buzzer Alarm for Live/Null Wire Judgment and Breakpoint Finder

My daughter had a problem with an electric light switch so had to call out an electrician. Turned out it was the new nylon carpet and a static electricity build up walking across it. I bought her one of these to check out the status of any wire or switch to see if it is live so saving time and expense of waiting for a professional. I already have one and so does my kitchen fitter after we had a new kitchen put in. He had never heard of them before!

I used them recently when checking the light cords in our bathroom, we have two. Turns out that one of them for the shower cubicle is not wired from the upstairs lighting circuit, but has its only live from a separate shower wiring. After switching off the upstairs lighting at the RCB, and checking both cords, I proceeded to unscrew the shower cord cover and to be on the safe side I used this tester which sounded the alarm as soon as I got close to the live wire, with red warning light. Wow, it made me jump, but rather that then get an imminent electric shock. So thank you to the producer of a life saving gadget.

Works fine.

Does the job.

OK for occasional user, but compared to my previous one the sensitivity is sketchy. I'm gonna buy another one and use this as spare.

Works great, however it makes an audible beep when it powers off (automatically) after I don't know 2 or 3 mins. I must admit I get a fright each time as I think it has detected a live circuit. Keeps me on my toes.

Dangerous product. Indicate power in one socket but not the other despite both working fine.Dangerous and should be banned from sale.

Bonus with having a torch!!!!
