I dont ordinarily write reviews but fairness mandates that I do so here. I almost didnt bother trying this app at all after reading all of the horrendous reviews from early September, the beginning of the 2015 football season.
But I did and over my office Wi-Fi connection it worked fine to stream a Big 10 football game on my iPhone 6. I didnt experience the crashes and issues many others did. It would have been nice to be able to rewind more than 30 seconds behind live action, but the app did rejoin the game after each commercial break without a problem. The video was fluid and decent quality.
Its not as robust an app as watchESPN but it got the job done - for me at least.
