Awful. If you try to load the sales part of the app to actually purchase new products or services everything seems to pop up right away. Try to log into your own account to manage your own services and it just doesn't work. At all. It just never loads. I don't know if that's intentional or not but it's terrible service either way. They're one of the largest major internet and communications providers out there, and their competitors have easy, stable, working apps. Inexcusable.
