1. I am a "power" user. This software accommodates my need to download a large number of videos in a wide variety of formats. 2. Download speed is incredibly fast compared to other downloaders. 3. Installation was a breeze. Straightforward install wizard without the annoying special offers/bloatware catches that come with the installation of many similar products. 4. User options to customize the downloads are comprehensive yet easy to manipulate. 5. The 10 day trial allows users to fully test the downloader before making a commitment. MP4 Pro downloader surpasses any of the several that I have used in the past. It performs equally well (fantastic!) for short download jobs and for large, complex tasks. I strongly recommend this to anyone considering a video downloader.
