Just as described and works well too

If you're working around large capacitors, you definitely need a discharge tool of some kind to make sure there's nothing left in those capacitors that can give you a shock. A 200V capacitor can absolutely kill you if it's not discharged, and they can sometimes hold a charge for quite a while when off.It doesn't take anything fancy to discharge a capacitor; I previously was using something homemade that was just some heavy gauge insulated wire and a resistor. That's essentially what this tool and others like it are too, from what I understand. The difference is the light. It takes whatever charge is left in the capacitor and lights up that light with it, so if there's no light, you know the capacitor is safe. (Ok, technically that light can burn out, so you'd probably want to test it at some reasonable interval.) It does take some amount of voltage greater than zero to power that light, so the instructions do make it clear that you should keep discharging for another few seconds after it goes out, but even if you mess that up or forget, as long as the light is out, the cap isn't going to kill you anymore.I got this for the light. With my homemade solution, it would definitely work but I would never quite know for sure. Was I touching the cap's legs right? Had I held it on long enough? I had no way of knowing so on big caps, I would sometimes end up doing it multiple times from slightly different angles and holding it on for much longer than I probably needed to. This thing just adds a little bit of visual confirmation, which is really useful.

Before I bought the ZIBOO Capacitor discharge pen I used either tweezers or a resistor to discharge capacitors. I don’t work with big caps, but I often measure them with an LCR meter and I don’t want to damage the meter. I know I can keep using the resistor/tweezers technique and all will be fine, but I wanted to have some sort of indication that the capacitor was actually discharged enough to be tested, and although doing one discharger myself sounded like an interesting project, founding one that’s already assembled and cost probably less than the components I would need was appealing.This discharger seems to work pretty well discharging down to less than 2V with no issues, and the tweezers are pretty convenient to use for in circuit work.Just for fun, I tested this discharger using a multimeter and a power supply. This discharger offers an internal resistance of about 880 Ohms when the voltage is above or around 3V (when the led is activated), which will allow for a fast discharge. Below 3V, the internal resistance increases quickly to the MOhm range under 1V (I guess this is due to the internal diode arrangement).In my case, this discharger is just nice to have, not essential at all although I find myself using it often. I like it and I’m happy with it.
