Excellent tool for network engineers
Model: 50km
This tool should be owned by anyone who ever has to work with fiber and their panels. I can't believe I'd ever accurately found the other ends of fiber without this. It makes the job so much faster when trying to identify fiber paths at opposite ends of the data center. It also feels sturdy and like it will last. I really hope that it lasts a long time. If it does, this is perfect. ... show more

Excellent quality, price, and strong laser
Model: 50km
This VFL works great and is low cost. With the increase in fiber deployment, inexpensive tools are invaluable. It's rewarding to find one that is both inexpensive and works very well. The only thing that would have been better is either including bulkhead adapters or a link to a kit of bulkhead adapters. The fit and finish of this VFL is excellent, and the laser is very bright and works extremely well. ... show more
