fyboptwu1pc 50mw 50km Visual Fault Locator VFL Fiber Optic Tester Fiber Optic Cable Tester with 1pcs Singlemode 9/125um FC Male to LC Female Adapter

Does what it is supposed to do. I like that guard that spins and blocks switch from being turned on.

Worked great for less than a month, then all of a sudden it wasn't bright at all and could not see a light on fibers at all. Loved how bright it was at first but due to it not lasting I would not get another.

The tool works well. The adapter provided is not the correct one. It does not attach to the light source.

Does exactly what my over priced work tool does. At a fraction of the price. Now I can send multiple red eyes to the location

This light is incredible bright even at distances beyond where most fault locators cannot be seen. Extremely useful for finding breaks in fiber optics.
