Of course it doesn't work
Doesn't do anything, can't push any buttons, display shows nothing. Q&A says no batteries required and then says later (2) AAA batteries required. No place for batteries that i can find without prying it apart. Would have given no stars but can't do that I guess.

works good
inexpensive small tool, works good for my shop, I have 3 testers and 20 dollors from HD, 200 bucks from pro store. that is pro level tester for sure. this one you pay 7 bucks, I use as screw driver and test voltage at same time. you need read manual carefully. display a little bit small. it is fine.

Voltage tester AC/DC
The tester is easy to handle, compact and light, it's easy to use but not really accurate with the DC voltage when tested in the engine wires, it was possible for me to read the voltage in the positive battery terminal, but not the continuity in the wires coming out of it. At home with the AC there was no problem with the same test.

You get what you pay for, not worth anyone's time
Doesn't work at all.. buttons are hard to press and barely lights up, you have to be in the dark to see the light then after a few days buttons are stuck and can do anything with

Very sensitive, but good.
I have only used it a few times. So far it works great. The buttons are sensitive, and the instructions are in broken English. So take your time and be careful.

Works ok, except
The "screwdriver" probe tip works, except on the new "tamper resistant" outlets, being that by design you cannotinsert anything in only 1 slot. (Thanks a lot little Jimmy, with your paper clip). I like that it shows the amount of voltagewhere you are reading, instead of just the presence of voltage like my "no contact" tester.
