Anyone have a balance310 5G demo or openbox?

I’m looking for a balance510 5g to test/buy if it’s a openbox, This is for personal use, and the msrp is cost prohibited. thanks

Where in the world are you? Why the B310 5G in particular?

midwest USA, i have two lines, a 5g, and a att lte, and i want full bandwidth of the modems, i have the balance 20x, but it chokes at 100mbps when using internal/flex module.
