This downloads quickly and reliably and is very easy to use. Recently, YouTube changed things up and thwarted this app, but the developer responded quickly with an update (automatically installed, if you OK that). He or she (yes, one person apparently) says YouTube does this from time to time so don't freak out (as the one-star reviewers did) if the Download button below the video disappears for a few days--it will be back. Please consider making a contribution to the developer or purchase the paid version. The free version works fine; the paid version has a few more options on it and, of course, helps support the developer's work. In the time-honored shareware tradition.
