Great Product!! Works Flawlessly with our switches!!
Flawless. Everytime.
Great product, great company and great price. We don't buy anything else now.
I have 4 of these on our network and no issues!
I haven't had these for a long time, but these seem to work well for us. Much, much cheaper than the OEM HP SFP's.
I purchased 40 of these and they worked as promised. Well done FluxLight.
Works well in a variety of HP switches with no compatibility issues. Very stable, no failure rate to speak of. Definitely recommend.
Very fast,,,
The component worked - no hassle - and continues working...
Units worked just as they said, had no issues at all.
