Good quality, solid and clean.

I’m so far very pleased by FS products, customer service and shipping !

item works great. Had to buy a second one.

Only took 3 days to receive, including the week end.

I needed these adapters ASAP and that is what I got from FS.com... I ordered at 3pm EST and they were in my hand the next day. The quality appears excellent, the packaging professional and I could not be happier with the purchase.

Works as intended. No issues.

The product I ordered is awesome, it does everything I need in a small, compact, but sturdy tool.

I bought this unit because my 5-year old one finally gave it up. Very handy for a quick connection test. Great for testing the fiber loss of the whole link and saved me much time for checking and replacing random parts. Well worth the price.

I bought this one with their optical light source tool together. The whole operation makes me feel great. Our fiber links are much complicated. These tools save us much time. Help a lot.

Its measurement range is suitable for my use. That's much wider. I like the USB port, because data transfer and storage can be very convenient.
