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.

Ganz präzis, effizent und pratisch. Es hilft uns viel bei der Wartung von Glasfaserleitungen. Auch der Servie von FS ist gut und zahtnahe!

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

für n schnellen und aussagefähigen Basistest perfekt geignet :-)

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.
