## Customer Reviews

### ⭐⭐⭐⭐⭐ Decent Identifier
*by B***N on November 3, 2023*

Fiber identifier and direction indicator checked out fine, tested in both directions. VFL and LED worked also.Easy to grip and operate the trigger for testing. No complaints so far.

### ⭐ Not all options worked.
*by D***  on July 19, 2023*

I only needed it to identify active fibers. But I thought the flash light and the red identifier light were added bonuses. However those last two options did not work. I will use it for my original need but I am unhappy with the overall product.

### ⭐⭐⭐ Works but missing VFL
*by D***E on August 2, 2021*

This model works, it just did not have the VFL as in the description.
