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

Es un equipo esencial cuando trabajas con redes activas para identificar las fibras, es fácil de usar y el láser incorporado permite identificar fallas, ahora lo llevas a todos lados. Definitivamente compraré más de esta marca.
