This is the only site where you will find everything what you need like movie songs trailer movies of any kind Hollywood Bollywood Tollywood everything is in my finger tips. I use it to download movie from here which I get at free of cost and in HD quality . recently I download In The Heart Of Sea really amazing picture quality.
It is best site to watch out everything what you need . Here I found so many learning videos about android everything what you want is present here from tip to top .
Its design is perfect to give you a simple access to their videos and here you can upload your videos easily no need to pay for that and eventually it is more fast than other sites .
But one thing which they have to work out with it that they should introduce a download option on the page which is most helpful for first time users.
Their app is excellent needs not huge space but work as fine as desktop and data consumption rate is low also. And their you find a new option to download the video to watch it later.
