I use the Verizon USB720 as backup and it's nice. Having it as a USB device allows you to use it on any computer as long as you can get to a USB port.
The one problem I have with it is that at times it just randomly shuts itself off and then sometimes turns back on. If not I have to unplug it and plug back in. It's annoying and I've contacted their tech support over and over on this. No luck so far. My guess there's a setting in my computer that is triggering it but yet to find it.
From what i've read regarding that issue it is that the card shuts off communication with the tower after a set period of idle time. Your best bet is to set up a website that refreshes every couple minutes as to prevent the card from timing out.
