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.

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.

This tool is so fantastic. I can just use it to evaluate the transmission quality in fiber links. It can do many works. The design is really good.
