*by E***. on May 4, 2023*

Big Clive did a review and teardown of this model test light on YouTube. I figured I'd get it because his review looked decent. A couple things- I added a length of heat shrink to the probe so only about 1/2" of the point is exposed. This is to help reduce the risk of shorting out what I'm testing to ground. I suggest this, for sure. The circuit board fits loosely in the handle. There's nothing keeping it straight in the tube. I cut n opening in a piece of heat shrink tubing and put it around the board... Now it fits snug, but I had to add a small spring between the board and the connection in the tube. Works well and sits straight now. Thinking about it now, I could have put two small loops of heat shrink (one on either end of the board) and I probably wouldn't have needed to add the small spring. Also (as per Big Clive's suggestion) I reversed the diode so it's green when polarity is correct, and red when it is reversed. Makes more sense that way. I also added a small piece of heat shrink around the diode to subdue it. The green is really bright. In the description it says 6-24v, but I am able to read down to about 3.2v accurately. Below that it starts to fade and bounce around. I assume it is because the microchip needs 3v to operate. I haven't tested the upper range because I don't want to kill it. I like this little thing. In the description (as well as in the images) it says it can read the voltage in forward and reverse polarity. The one I received does not. It only displays a voltage reading when the clip is negative and the probe is positive. This may be an issue in certain situations. The description also says it reads "frequency voltage"... I have no idea what that means, but I doubt this probe does anything with frequency. Overall, I am happy with this tester so far. It didn't take long to modify it to my liking, and it feels like it'll last for a good amount of time. I don't use these testers every day, so your mileage may vary. I don't think it'd hold up in a severe duty environment, but for a home gamer or light shop work, it is fine.
