Fielect Test Screwdriver, Voltage Detector Pen Light Circuit Tester Electric Test Pen Screwdriver Neon Tube AC/DC 100-500V Clear 1pcs

Gets the job done.

I got the test pen on time, and thanks for the services. The product is good enough except for the light is a little dim. Overall, I am satisfied with the product.

When working with live wires, checking a hot connection is tremendously valuable, and knowing that the tester pen works should NOT be in question. This is relatively inexpensive and did what it said it would. Out of the box from the mail, the light inside is easy to see.I purchased it for a friend's project and left it with him so he can have one on hand. I showed him exactly what I did, so he can be certain to use it to check the wires when connecting lights and other items to the boxes in his apartment. It is small and sturdy and I know it will be used again and again with simple lighting installation and other home projects.FYI, I did not choose this one due to its brand... I recommend it based on my personal experience with it.(in my opinion, this type of product is either a 1 star or 5 star... either it works correctly or not... this one worked, so I give it a 5) ;)

It worked for me on wires I needed to test. But as some of comments said it is a very very dim light. Difficult to see in daylight.

Product works, BUT the light is very dim. If you are outside in the sun the light is so dim it is impossible to see unless you shade the light with your hand. My old light worked well in under all conditions until I dropped a hammer on it (by mistake). This one is not nearly as good as my old one. I would not repurchase this item.

The light doesn't work, even when electricity is detected. It's extremely dangerous and a waste of money. Do not buy it.

Good

The light is way too weak for 120V. It's ok-ish for 240 but that's a minority of use-cases.They work, just not meant for the US IMHO
