NitroFlare is a file storage and movie downloading service that is very deceptive - don't use it. First, they promise you unlimited downloading but there are indeed limits that you won't find out about until you pay for their downloading service. Second, the picture quality of the movies can be terrible to the point that the movies are unwatchable. There are also often problems with the synchronization of the audio and video, again making those movies unwatchable. When I complained about this they said that they are not responsible and that I should contact the "owner" of those movies. Yet they pay people to upload those movies and then charge others for their "premium" download service. That makes NitroFlare responsible for the quality of the content - a responsibility that they don't live up to. Third, when I complained about this, all of a sudden my download times went through the roof. Clearly they don't like criticism.
I recommend that no one use their "premium" downloading service nor their file storage service as NitroFlare is dishonest, childish and they clearly don't know how to run a business.
