It is super good.

The same brand compatible converter module I inquired from other supplier in China is much more expensive than FS. Meanwhile, their quality is trustworthy, FS's after sales service really does well. With their local technical support starts, I will cooperate with FS on more products.

Good value and free shipping, excellent job! Fiberstore has become my first choice when I need fiber products.

I will give this product five stars because we have been using them so far on our fiber project, and to tell you the truth that we are extremely happy with the product. Working perfect!
