Customer feedback

James Rice

"Great. FLEXBOX does what it says on the tin! - just connect, configure Transceiver and be happy."

Klaus Degner

"The FLEXBOX allows us to use 100MBit/s to multi-gigabit transceivers in our product for a wide range of customer needs. We can not solve them without this magic box!"

Peter Splettstößer

"Die FLEXBOX ist die beste Erfindung im Netzwerkbereich seit langem! Einfach die zum Endgerät passende Konfiguration auswählen und den Transceiver damit programmieren – fertig. Schlechte Verfügbarkeiten und hohe Preise von Originalzubehör gehören nun der Vergangenheit an. Kurzgesagt: perfekt!"
