Works great and does exactly what it says on the tin.

Thanks very much! ^^

This is EASILY the best Greasemonkey script that you can get for Youtube.

1.) It now has the ability to automatically find the highest quality version of a video. 720p, Stereo, whatever. BIG kudos to the hands behind the code!

2.) It does not need to refresh the page. This is so much more convenient than other solutions available for Youtube.

It's one of the most impressive scripts that I've found.

Nuff said.

Works as advertised and the author is always on top of things whether it be a request or bug report.

works great, exactly as advertised.

Works as advertised.

simply the best and more complete greasemonkey's script for youtube.

It's unbelievable how useful this script is. Works beautifully, and updates often enough to stay current with any updates yt may have. YouTube HD Ultimate CERTAINLY has the most features compared to any other script, so this is the only one you'll need.
This gives you all sorts of video-size controls, HD controls, playback and color controls, video downloading options, and several extras like Cinema mode.
If you've ever watched a video on youtube, you need this script. You'll never want to go back to the default youtube.
Can't live without this!

Really great job...

I generally dislike how YouTube runs things these days, but alas, so many people use it that there's not much other choice. Thankfully, this script is here to make watching videos on YouTube so much nicer.

Some things just seem like they should be built right in, while others are just nice functionality. All in all, this is a definite must-have script. Plus, even with the constant changes on YouTube, the author is excellent at keeping it up to date, ensuring you don't have to suffer a broken experience for long at all.
