I have only had Vooplayer one day but in that time i have found it so amazing! For me i like that i can brand the video to go with my site so it looks part of it and not an addon at the last moment! You have total control of how it looks and how it works. You want to hide the controls, its done in one click.
Most of it seems very easy to use but i do feel the UI could be streamlined to de-clutter a little! I just know this is going to work for me over and over again!
