What customers say

Great. FLEXBOX does what it says on the tin! - just connect, configure Transceiver and be happy.
James Rice Jump Networks Ltd
Have been using FLEXOPTIX transceivers for a few years now in a carrier/telecoms environment for various vendors and they've never disappointed me. After having the opportunity to be able to program them myself on demand, I've realized how many hours I could have saved until now with FLEXBOX! No large stocks, just a few generic SFPs in stock waiting to get programmed when needed. Awesome!
Michael Nicolaou Senior Network Consultant, CDMA Services Ltd

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.

Arvid Picciani CEO / devguard GmbH

The flexbox has been an amazing tool for our Equinix AM5 deployments, we have used many brands previously however the flexbox was superior right from the start, especially when working in the datacenter and not needing to hold my laptop in my hand but my phone, which is just amazing for rapid deployments.

Looking forward to keep using the flexbox in the future! :)
