Tomorotec 2PCS Voltage Tester Screwdriver Set - Multifunctional, Magnetic Tips for Enhanced Efficiency, Dual-Use Design with Neon Light Display for AC/DC Circuit Detection, Comfortable Anti-Slip Grip

These work really well, showing green even if you touch the two ends of a screwdriver with your own fingers. Low voltages show up as green. High voltages the Red lights come on also. The pics in the add "suggest" these will work like a NCV (Non Contact Voltage) tester. I have to say, I had poor results for that but I didn't buy the, as a NCV tester anyway. I have a nice NCV tester I got from Amazon already. I wanted a screwdriver (flat head and phillips) that I could use with insulated rod for when I'm working on live circuits. These fit my needs 100%. They come with spares sets of batteries which is a nice touch considering the ones installed seem just fine. Nice pair of screwdrivers and would definitely recommend.

These are light weight and easy to use, with colorful lights. It's nice to have 2 of these, flat and Philips screw-head, so I can also use them as backup screw drivers.

One works,one no

Never had such an easy to use Voltage tester! Great product

Easy to use tester

It is a very low quality product that is not worth even its relatively low price. One of two testing pens did not work. The reason - 3 small batteries that provide power were stacked incorrectly (they should have + side connected to - side of the next battery, but that was not the case). The batteries are kept in place by a spring which flies away when you open the cover to replace the batteries. The batteries do not easily come out and, when forced, come out with internals thus breaking the device. And on top of all that the product description is uncomplete - does not mention that the product needs batteries (and of course does not mention the batteries model and how long they last).
