It's a good deal but I'm still thinking about it. I've used the Xbox app twice now and it's shit the bed both times. I imagine it works well now but I just don't wanna risk it.
The predictions part of the app is a great feature though. It really makes me root for a guy when I'm competing against my friends' picks. This event is going to be really fun since a lot of the fights can go either way. I just wish they'd lock in Facebook picks already. You can change them whenever you want.
