I never used foxfi untill about a week ago. Lost my home internet due to storms the day I got Black Ops2. Cant remember the name but I downloaded another tether app that was free and not only did it not work it totally broke my wifi. Reflashed backup download the free foxfi, not realizing there were restrictions, ran BO2 as good as my home net, then mid match it dropped on me. Well it was there new time limit. I gladly paid for it. If you are not gaming with it dont buy it if you dont want to to you just have to restart now and then. There site says it is random between 10 and 30 minutes. IMHO though it is well worth the 7 bucks. I just got an *gulp* *choking* (sorry for the swear wrd to follow this) ipad that is wifi only and now I can have net on the go.
