The product itself seems to work fine, better than you might expect at this price point.

Bought it over eight months ago. As a technician installing fiber optic cable services I found this to be an extremely useful addition to my tool kit.

Works as described - just make sure you purchase an extra FC to LC or FC to SC adapter if you want to do bi-directional testing

I've used it on several projects to see if the fiber loss was out of tolerable range. And it was surprisingly accurate. As for me, it's really a huge help.

Pretty straightforward to use. The LED screen is sharp and easy to read, I was able to test SC cable. So far, it has helped me a lot to troubleshoot fiber link connections and saved a lot of time.
