The stripping tool is pretty neat. I was not aware of this stripper style. It’s a bit of a fiddly trial and error process to figure out where to set the guide screw, but if you’re stripping the same size wire many times then it seems to me like quite a neat little way to do it. In the video, I strip a 12AWG wire.
I’m a little disappointed that there aren’t any square-head screwdrivers in this set. And I have to admit I’m not entirely sure about the voltage tester. Sticking a metal thing into a live socket and then touching the other metal end gives me pause. If the internals shorted out somehow, then that’s potentially a very bad day for the user, who becomes part of the path to ground. (You’ll notice in the photo I used a GFCI outlet to test it.) And if you stuck it into something greater than its 250V rating then I imagine you could seriously hurt yourself (or worse). Then again, most of us don’t routinely encounter voltages above 250. In any event, I’d feel a lot safer using a non-contact voltage detector, personally, but those admittedly aren’t foolproof. Some multimeters have a live-wire detection mode where you stick a probe in but don’t have to touch anything metal yourself, which I also like. But, to be fair, it’s probably harder to fool the basic voltage tester screwdriver in this kit—but be careful about lighting. The little indicator lamp really isn’t very bright and would be easy to not see even under bright indoor illumination. I thought it wasn’t working at first because I had my under-cabinet lights shining down on it. But you could do a lot worse than this tester. There was a time when someone might’ve suggested just quickly brushing the back of your hand across a wire to see if it’s live. And if this cheap little gadget stops you from trying something dumb like that then I suppose I’ll have to give it a pass. But ideally you’d start off with a technique that doesn’t put your body in the current path, and just use this for confirmation.
The carrying case is a bit awkward. It’s fiddly to slide the tools in and out of the elastic loops. But it seems like a nice enough way to keep the tools nice—and you do want to avoid beating these around so you don’t damage the insulation.
Let me say, though, that whatever tools you’re using please be careful around electricity. Don’t attempt anything if you’re not confident you understand how to do it safely. You really shouldn’t be working anything live if you can reasonably avoid it. And I know that might sound a bit rich given that these tools are specifically insulated so you hopefully won’t get shocked if you try it. But the best thing you can do would be to shut off the breaker to whatever you’re servicing but then use these insulated tools (and gloves) anyway, just in case you switched off the wrong breaker, or someone doesn’t realize you’re working on it and switches it back on, or something is wired horribly wrong and voltage is backfeeding from somewhere despite the disabled breaker. If you absolutely have to work something live, please be very careful, wear gloves and eye protection, and try not to apply any loads before connections are complete because they can cause sparking.
