FTmall(TM)AC Electric Voltage Detector Sensor Tester Pen 90~1000V

The best tool that I ever purchased, I would recommend this to everyone. I just solved a electric issue with this device that I been dealing for 18 years. 100% recommended.

I took a chance on 2 of these as the batteries corroded in my Greenlee one I've been using for years. It's made to look just like a name brand version and being as it's a pretty simple device I took a gamble that they'd work ok even though there were some negative reviews. Well, I'm returning them, the reviews were correct, one of the 2 I received wasn't too bad, I'd say it was 75% accurate, certainly more sensitive that the other one I received. That was was less than 50% accurate even along side an actual wire, it did not work at all in an outlet. Ultimately this is a life safety device when doing electrical work and even a 25% chance of failure is way too high when you're working with electricity. Someone is going to get hurt if Amazon continues to sell this product.

it's the most speratic working glow stick which makes it useless

I received this noncontact tester on time.this not very sensitive.And bad even though it puts off the battery,because he always included. but to the price it corresponds.

its just a tick tester, not really much to say about it, its durable an has held up inside the paper mill i work out so no complaints.

I brought these just for the heck of it. I have many of them. But this one is really nice. It comes with an LED flashlight.

Do not waste your money on this item, it does not even function properly even a small percentage of the time. The quality is very poor, and the item poses a safety hazard to the user since it may indicate the absence of electricity when in reality there is electrical current present. Also, I contacted the seller to let them know the item did not function as described and they wanted a picture sent back to them, and ultimately wanted me as the buyer to pay the return shipping to China on this defective meter.

Great tester
