What customers say
You guys rock! I have had the opportunity to use the previous version of FLEXBOX with my previous company. I cannot believe the progress you have made just in a year. Battery pack? Mobile reconfiguration? I am truly feeling lucky to have met you guys at Cloudfest. I will be honoured to demonstrate your products to startups as great examples to contribute to tech sustainability.
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.
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.
When in possession of the FLEXBOX it becomes and indispensable tool in general, and also specifically in managing remote Mobile Base Stations fiber connectivity.
Using the FLEXBOX either with PC or Smartphone is really plug and play with no annoying incompatibility issues at all.
The FLEXBOX together with ease of order and superior delivery times makes it literally unnecessary for us having any significant SFP stock.
