They advertise fast download speeds if you sign up for a premium membership. I signed up for a one year membership for $55 but found the download speeds were not as advertised. Their advertising leads you to believe that you can download a 300 to 400 MB video file in less than 5 minutes with a premium membership. In most cases the download times turned out to be 3 to 4 hours for a 300 to 400 MB video file!!! I complained to Filesonic. First they told me to download and install Chrome as my web browser. (I was using IE9). Downloading Chrome did not make a difference. Then they told me to download and install a download accelerator. That made no difference. Then they told me to download and install Firefox. At that I told them I was going to request a refund. I have used numerous other file sharing sites such as Rapid Share and Fileserver and using those file sharing services as a free user I got download times of about 20 to 25 minutes on a 300 to 400 MB file. I was able to get a full refund of my $55. Would not recommend anyone pay money for Filesonic’s premium service.
