I think it is expensive for just a video player, but it would be very beneficial to be able to put YouTube videos on the web without ads or the YouTube logo.
AppSumo has a player very similar to this for half the price. This is better because videos can be easily downloaded with a right click.
However, the video downloading solution is not better than that; I need Anti Video Download Helper solution.

It uses jQuery, so if you check with pagespeed, the jQuery-ui.js from killerplayer.com is the bottleneck. it is faster than the YouTube player, but rarely has problems with not displaying.

It seems a bit of a chore to go to the site each time and configure the colors and other settings. If possible, I would like to have a wordpress plugin or the ability to save settings.

It is stated that analytic functions and other features are scheduled to appear, but I am very disappointed that they are not offered at this time.
