What customers say

Your FLEXBOX rocks. On our Linux workstations we can easily change the vendor and thus save costs. In addition, we are also convinced by the product quality, the support and the handling of the order. Thank you!

Martin Verges Managing director / croit GmbH

Now that I’m done configuring my equipment, I use FLEXBOX to impress associates.
I’m an IT Hero just for the savings, not to mention the FLEXibility to stock one type for each adapter.
Keep up the good work!

Nikos Papandreou IT Admin / Geitonas School SA

The FLEXBOX was easy to set up and use, and the programmable transceivers worked seamlessly in several different brand devices. This will make our spares much easier to manage.

Shaun James Engineering Inspector / Tata Steel Strip Products UK

Woa, i can get next day delivery for any vendor. That’s a game changer. Also thanks for making it a smartphone app, this fits my workflow well.
