Shipped fast easy to use. Marley was a pleasure to deal with as always and updated us all the way. Excellent Service !

I told my project manager to order the FS BOX v4 because it would be a handy tool besides the FS BOX v3 that I own. After I used this FS BOX v4 with my iPhone 14 Pro for 2 weeks I can only say, it's the most handy tool I've used! With the “weird” broadcast equipment we are using it helped us alot. The SMPTE2110 standard don't tell any manufacturer what their devices QSFP/SFP28 ports are supposed to support, I mean, they don't do networking equipment usually. It has been a very good tool for debugging and developing the latest technology for video delivery.

Handy device, came nicely packaged and with a carrying case. Very easy to use and re-program FS SFPs. You can use the App via bluetooth to connect to the tool, or you can plug it into a desktop/laptop via USB.

Great product! Easy to use. I updated the code of my transceiver from "Generic" to "Mellanox". My cable now works as expected.

Thanks for the support.
We will need to use this again

The FS Box v4 has been a lifesaver in that we are now able to code our SFP's for various products which reduces time and free's up our team to continue with other work.
I can definitely recommend this product.
