I bought now so 2 Converter and since about 4 months (Duration 24/7) use.
A par values:
Ping time between my computing> Switch-> Converter> fiberglass> Converter> Switch-> other computer: 0.473ms
Transfer rate same route (IPerf) 992Mbit / s (unfortunately limited here my network card, however, the nearly full speed)
I can therefore only recommend this converter. 1A product can at a price which no other manufacturer to keep up.
Speed, Robostheit and everything else fits perfectly.
Definitely recommended

So far, I'm still really happy. No broken, no problem. 1A
