Sysotek Visual Fault Locator - Rechargeable Red Light VFL Fiber Optic Tool kit - Retractable Head fits SC FC ST - Optical Laser Light Pen Network Cable Fiber Tester with Protective Case and LC Adapter

I’ve been working with fiber optics off and on for a while now and just picked up this fiber optic visual fault locator, and honestly, I’m super impressed. If you’re like me and constantly dealing with cable issues and trying to troubleshoot stuff this tool is a lifesaver. Right away I noticed when I picked it up you can tell the VFL feels solid. It’s not one of those cheap plasticy tools that you feel like is gonna snap in half after one drop. It’s got a good weight to it. I’ve dropped it once accidentally, and i can't even tell. It’s super comfortable to hold, and perfect size and it fits in pocket easily or i can always tuck it away on a panel. The best feature is its rechargeable and the battery lasts long time. Uses USB c and I've used different ones to charge it no problem. I've let my colleague borrow this and he needed it to stay on for long time while he left his site and it works while it's plugged in. I’ve had this out on multiple jobs now, and it hasn’t run out of juice on me yet, which is a BIG plus when you’re in the middle of troubleshooting a huge network or need to travel and don’t have time for your tool to die. Ive used other cheap ones and they time out and anyone who uses these fiber light pens know that feature is horrible and makes them useless. The laser that comes out of it is super bright, so even in somewhat well lit spaces, you can easily see it shining through the fiber cable. The other main feature is that how you turn it on is by twisting it and the head pops out or retracts and doesn't need dust caps and is totally protected when it's off. It has Super nice hard protective shell case. Honestly if you need a vfl and are thinking about this one just do it. What an upgrade to other crap I've used. The laser is bright and I've tested long runs couple miles and no problems. Makes me laugh the advertising of the high powered ones for sale and going these crazy distances which are impossible. Any experienced tech knows that this type of laser light has a max distance in a fiber cable doesn't matter how strong the laser is. A fiber vfl is a lifesaver for troubleshooting fiber networks but its honestly actually essential and this ones all you will ever need. I’ve tried others, but this one’s definitely the best for the price. You get what you pay for. Definitely recommend it and super happy with this purchase.

This new technology is really great! All the qualities of a standard visual fault locator based on my use so far, plus more! - Small/Compact, but with a little weight to make it feel 'quality' built. (The retractable head keeps it compact) - When I twist the unit on/off, the connector head pops in and out. Being able to retract it keeps it safe from dirt and/or damage when I accidentally dropped it. - Rechargeable, really handy as well, so I don't have to carry spare batteries. - The charge lasts a long time (although I haven't let it fully run down). And' there is a battery indicator that shows remaining life. - The USB-C charging port is a definite bonus, and there's a small charging cable included. - It has a fabric covered 'hard-shell' protective pouch (kind of like the kind you get for a pair of really good eye glasses) that the unit (and accessories) fits in nicely. This is a sleek little unit and will fit easily into a man or women's coat or vest pocket. I'd definitely recommend it based on my use so far.

1 out of 5 stars – Stopped Working After Light Use I bought this VFL thinking it would be reliable, but it stopped working after about two months with barely any use. I only used it a handful of times on basic jobs, and now it won’t even turn on. Definitely not worth the money if you’re looking for something durable. Disappointed.

So far so good this send to be good from this seller the other two I offered from a different seller man they were no good.

Fast charging and battery last a lot!

Item stays with link runner diagnostic equipment to make finding fiber in rack simple when not connected to switch.

Good solid quality tool. Great value, when compared to repeatedly replacing batteries. I have been using this for a week, straight out of the box. The charging power level is still the same, no loss. The light is very bright. I have shared the link with my coworkers, for purchasing.

Works great, the only thing I noticed it charges to last red led light.
