Here is the easiest way to download any video from Youtube.
While playing the video on youtube.com, Copy its location from the address bar like www.youtube.com/watch?v=sasad7657dms2
then add the word ‘kick’ between www. and youtube.com/link…….
That’s it, Download without any other software or going to any other site, as their are many but this method is the best one according to me. Enjoy :)
