Aiseesoft Mac Video Downloader is a program that really comes in handy when you wish to save some clips from video sharing websites directly on your computer. You can work with this application whenever you want to fetch a video for the offline playback or to watch it on one of your media devices, like a mobile phone or a tablet.
The utility allows you to download clips from websites like YouTube, Vimeo, Metacafe, Facebook, and many others. You can configure the app to automatically convert the videos to various media formats as soon as the download process is complete.
Another good thing is that the program supports a wide variety of media formats compatible with iPhones, iPads, PSP, Xbox, and others.
My only concern regarding this download manager is that it doesn't let you select the preferred sound quality when it converts videos to audio formats.
As for the rest, Aiseesoft Mac Video Downloader offers you a fast and easy way to grab videos from the Internet. So, I'd say it's worth buying this utility, if the aforementioned disadvantages do not mean much to you.
