Review: Great Tool, useful on the field - I work at a fiber optic internet company, it’s been very useful and it has all my needs on the field. We get optimeters for testing light, they take forever to turn on and there is no VFL on our models. It’s so convenient having instant access to check light levels that you can store in your pocket all the time. The VFL is handy and bright, only downside is after 5-10 minutes it automatically turns off. I wish if the VFL is on then it won’t turn off but it’s not a big deal. I highly recommend calibrating to your fiber optic wavelength and light levels, the out of box experience is good with about 3 DB off but it’s great for a general estimate when it’s not very important. After calibration even after a couple months it’s been accurate and works very well. The battery life is pretty good, it uses 2 AAA batteries and it lasts me about a month or bit more. I love the Ethernet tester that is built onto the removable slot on the bottom. On the field I also work with CAT 6 and it’s great having it on the tool, I never have to carry around a separate Ethernet tester or ever run to my truck to find it. It’s helped me out in situations I never expected. The only major downside I had is the screen. When I first bought it, after about a month half of the screen was not working and was affecting my readings. I exchanged it for a new one and been very careful with the screen and making sure it won’t get dropped or damaged. It’s been a couple months and it’s been working just as it’s new. Overall, I love this tool and it will be a must need for me when I’m on the field.
Review: Good product - This is a good product for its price. It is accurate, it's lightweight and it for sure. Does the job I've had it for over a year now? And it is my go to I do fiber. Optics, so I have to have an accurate version of this, and this one has been an insanely good one. It's durable and can take a beating
