What customers say

In our test environment we use the optics over and over in many devices. Programming optics with the FLEXBOX is as easy as 1,2,3!
Erwin ter Hofstede CEO, EC-Hosting

First of all, I must salute the both geniously clever and absolutely gorgeous packaging: frankly, my I.T. colleague and I had blinking stars in the eyes when opening the boxes. I had a previous experience with both proprietary and generic transceivers/DAC, and I must admit that your hardware is doing great, everything feels very professional, and thanks to the FLEXBOX, the configuration is super-easy, install the app, insert the transceiver, select model, et voilà! The switches are happy. Thanks for the candy!

Julien BENNET Technical Director / Areal

I have my own company, and I work as a network consultant for different customers, especially in the wind turbine business. I am often on turbine sites in the middle of the ocean, where I need a SFP of a certain type/vendor. By using the FLEXOPTIX FLEXBOX, I have solved a very big issue, just by having this tool and some FLEXOPTIX SFP`s in my bag. Then I can solve the issue, and get the site up and running immediately. This saves another trip to site (often by helicopter), and a lot of money and time. I am very exited about this product, and will certainly recommend this product to everybody.

Spending a few minutes of my time, first and foremost expressing how much I’m impressed by your friendliness, is the least I can do. Friendliness was followed by super-fast order processing and delivery. In a few words, unboxing and using your Flexbox is an utterly awesome experience. As in brilliant. Also saving us loads of time ordering optics. In addition to all of this – you deliver particular good build quality, too. You’ve got me impressed, thank you!
