Review on MAXRIENY Voltage Detector: EBTN LCD Display Tester Pen with Adjustable Sensitivity, Non-contact AC Electricity Sensor by Mike Messerly

This is not a complete replacement for a multimeter but I wasn't expecting it at this price point. Plug the wires into the connectors below and you have a fairly accurate multimeter with the basic functions you need. I found it funny that the wands were an inverted color on the inside (as opposed to the actual color of the rest of the wand) when you removed the tips. I've shown a few things with the multimeter mode in my drawings, such as checking for continuity and measuring voltage. The screen is much easier to read than most similar devices with its inverted color scheme. There is a flashlight at the top of the tester, but it will not replace a full-fledged flashlight. Let's get down to what this device really is. As a non-contact tester (well, I really got it), this thing works really well. The less sensitive mode requires proximity to the source to be measured, but will not work with highly isolated connection points. The more sensitive mode works fairly easily anywhere near any voltage source, even just a few inches away. Everything is as expected. Voltage or proximity to source is fairly easy to read (during non-contact testing) with well-lit bars that have multiple levels and colors. pretty nice too.
