Has a little coin cell plus some electronics and an LED so as well as a check for live mains like a neon tester it can check continuity of fuses, give an indication of whether an AA type battery has some charge in it, plus non contact detection of mains electric current - like from a live wire behind a wall switch. Finally it has microwave leakage but I have not tried that. Only improvement would be a better LED as the red light tends to shine down to the tip of the screwdriver rather than out sideways as my previous (lost that one) did making it not too easy to see in bright light. But it works and is so cheap you can keep a couple handy.

I have carried one of these in my pocket since discovering them many years ago. This is the FET based design which gets brighter if the tip is more positive than the cap. Very useful for a number of quick fault- finding tests but learn its behaviour as it is very sensitive and you always need to check against a known condition. This particular test screwdriver with the blue tint is the better quality version given that they are all Chinese anyhow. I made a plastic cap for mine so I don't poke myself through my pocket.

The mains tester bulb is particularly handy so you dont go poking around high voltage wires and possibly getting a lethal shock. I now find it indispensable. Good value. I don't know why I havent bought one of these before.

It might be me, but I couldn't make this pen do half of what it claims on the package. It says that it can tell you if there is power in a cable by tracing it, so I switched on the kettle and tried to trace it, but nothing showed up. I also tried with the iron, and the same result. There are other claims there I couldn't reproduce. Ok, here is sthg positive about it: the neon light is good, ie highly visible, probably even with the sun shining on it! Well done for that. If it claimed less, it would have got more stars!
