📊 Longruner Multi-function Tester 1.8 inch Colorful Display Pocketable TFT Backlight Transistor LCR-TC1 - Diode Triode Capacitor Resistor Transistor LCR ESR NPN PNP MOSFET LW21 Review

This is a very good product. In this world of self-testing and/or self-healing consumer products, this is a must. There are many products that are significantly more expensive, many and sometimes almost 90% of the functions do not use them. The most valuable tool is your mind combined with intelligent thinking backed by intellectual logical experience. In itself, this is a high-quality product that cannot be compared with inferior quality. That means you can't tell it's cheap or toy based on…

As much as I love this thing, I wish it only came with a 9V battery connector. This device connects to a micro USB charger to charge the internal battery. I'm sure this is a one-time issue in my case, but on a full overnight charge the battery lasts me about 4 hours even when it's turned off. I have to use it on the charger most of the time, which is a nuisance given all the cables cluttering up my desktop. Update: I finally took it apart (4 screws that fell out) and found a very bloated…

I purchased this product after purchasing a DIY kit from another vendor that was poorly designed and did not produce the results I expected. I decided to reuse the TFT and some of its other elements for other projects and just bought a long runner tester. Not much to say, take it out of the box, FOLLOW THE CALIBRATION INSTRUCTIONS! It takes less than 5 minutes and works great. I've used it on every build since then. Just take a resistor, cap, transistor or whatever, stick it in there, and in a…

- UPDATE AT THE END - This will be a quick review, I'll update as soon as I use it. I have 3 different testers in this style, this one is my favorite. It has about the same accuracy as other devices, but this one has a super nifty zener port and a less useful but interesting IR serial data port. This is the only color/scanning display with a built in lithium ion battery that I have. My others are much simpler, but they have 3-cell managed lithium-ion batteries that I built myself (that's a…
