This is the best downloader without fail. It's easy to use and for me has worked every time. The drop down menu makes it easy to see the options for the filetype you want to download. This guy is genuine and enthusiastic so if you use this then buy him a coffee.. i'm sure every little bit helps and it's worth a few bucks if you want the ability to quickly and reliably download from youtube. I have my FF browser loaded with security plugins/add-ons etc and it still works a treat.
