Customer feedback

Elmar Gruber

"Absolutely Flawless! Long time ago we were used to work like this. Thanx to Flexoptix we're back to that status of quality we're searching for! Ultrafast delivery and really plug & play from start to end. No we're able to react on needs much more quickly thanx to FLEXBOX with having modules on Stock and instantly program them due to customer's need."

Bronislav Robenek

"Ordering and using FLEXOPTIX transceivers was far quicker than even getting a quote from traditional vendors. Using the FLEXBOX is super easy and fast - 5 minutes to get transcievers ready including unboxing and enjoying packaged marshmallows."

Oliver Baur

"Die FLEXBOX ist endlich einmal ein Gerät, das einfach nur so funktioniert, wie es soll - und das auch noch richtig gut. Das verstehen wir unter Flexibilität und Investitionsschutz."
