Review on 🔌 D YEDEMC Fiber Optic Cable Tester: Portable Power Meter, Visual Fault Locator & Universal Interface (OPM&VFL) by Anthony Heinrichs

Bought over 8 months ago. As a technician installing fiber optic cable services, I have found this to be an extremely useful addition to my toolbox. I mainly use the 1490 wavelength. Small but gives very accurate readings and the black rubber cap keeps dust and other particles out of the lens when not in use. As an added bonus, the built-in RJ45 tester is very useful. I'm just skeptical about using AAA batteries instead of AA batteries, but overall this is a great and long lasting product.
