It is a very cool addition for the Fly Digi controller. It's great that it acts, in addition to being a hub for your wireless dongle, it also gives you two more USB ports, so you don't lose any connectivity for using it. That's cool as hell. The animations are novel and it works just fine. You update it through the Fly Digi app for whatever reason and you're good to go. It's not necessary at all, which I get how it wasn't packaged with the already not cheap Vader V, which in and of itself is probably the best controller I've ever used. You are given no more function for your money than a place to put your controller when you're not using it that looks cool and charges it when not in use and if that's enough for you then buy it. It was enough for me. You lose absolutely nothing by not having it though.
