content: I am using it for a class that I am taking 4 days a week 3 hours a day and this works really well  considering what I expected lol only every once in a great while will it get choppy  I really think its because of where the person who is speaking is located to get a signal but Ive had really good service from this app up till now. It really has not been the headache that I expected it to be so I must say Im pleasantly surprised and would recommend it...
