Good extension to control speed, I personally use keys + and - to control it (like a similar chrome extension)
Good customization :)

Works simply perfect with Vimeo which is exactly what I needed it for. The customisable shortcuts are a nice plus too!

BEST TIME SAVING APP EVER.

Seriously, had some coursework with professors from Texas that talk like snails crawl: sllllooooww.
With this extension, their unbearable 4 hour videos got reduced to a more reasonable 1.5 hours at a quicker pace.
I started training my brain to hear info faster in videos and as a result, start most videos at 2.0x speed or more just to save the time.
Would pay for the pro version considering how useful this extension has been and amazed that it's free ninety-nine!

Amazing

É ótima ferramenta! Agiliza, e muito, meus estudos!

Hi.
Please add the option to move forward and backward frame by frame the videos with their respective keyboard shortcuts.
Regards.

Simple and effective. Thank you.

Having video speed control from your keyboard is awesome. Also nice to have a bunch of speeds not available in default html settings. I got it for youtube, but it works in most videos you can see playing on a website, even background videos meant to be part of the site design. Good stuff thanks.

Works well. Works on Udemy also.

Video Speed Controller is great! Small and unobtrusive, and it does exactly what it says! Well conceived, and elegantly executed!
