## Customer Reviews

### ⭐⭐⭐⭐⭐ Bright enough to locate faults easily.
*by S***R on September 19, 2025*

Works as it should.

### ⭐⭐⭐⭐⭐ Work smarter not harder
*by K***. on January 28, 2026*

Use this for work. And is works great had it on a 12 mile stretch of fiber, made it easy to find the break.

### ⭐⭐⭐⭐⭐ Extremely bright.
*by S***E on December 3, 2024*

Very bright! I was able to visually confirm connectivity over a dark fiber span that was 17km in distance. Most VFLs would never reach that far. Battery life is slightly less than other brands, usually lasting a week or two with heavy daily use but the extra power is well worth it. It's so good I bought several more for my crew.
