What customers say
When you unpack it, you immediately notice: A lot of time and love was invested in this great device. In just a few minutes everything is ready to go and the first transceiver can be configured. The app responds quickly and is well laid out, and the search function makes it easy to find the right configuration. The FLEXBOX is ideal for us because we use switches from many different manufacturers and can thus react flexibly to changes in our infrastructure at any time. Even on site, we can make adjustments at an instant thanks to the support for mobile devices for configuration.
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!
FLEXBOX is not only awesome but also easy to use. One of the standout features of FLEXOPTIX is their compatibility with various vendors. Whether you're working with different hardware providers, you can rely on FLEXOPTIX to work seamlessly across different platforms.
Moreover, the support for FLEXBOX and FLEXOPTIX is exceptional. If you encounter any issues or have questions, you can rely on the support teams to provide timely and effective assistance. They are dedicated to ensuring that users have a smooth experience and can make the most of these technologies.
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!
