I wasn't sure about Killer Player and how it would work for me, I just recently spent 2-3 times this price for a more advanced WordPress plugin that does what Killer Player does and quite a bit more - the drawback is the number of sites is limited.

I only actually use YouTube videos for my WordPress sites and this is great because there is no plugin to install and the process is amazingly quick and simple, just add a HTML element to the post in WordPress.

There are a few templates that make it look like the video is hosted elsewhere in Wistia, Vimeo and some others which is a nice touch.

It works really well and there were no issues with speed or responsiveness.

I highly recommend this deal as you can use it with any site and it is unlimited.
