Revised Review (used to love this, but it stopped working)
By flourescentvest (Pcmac user)
This app has now stopped working for, I’m guessing, High Sierra. Emailed the developer a while back. No response. I did truly love this app and will change my review if the app starts working again.
My earlier review:
I bought this really to support Pipifier, another incredibly useful addon for Safari. However, this app is even more life-saving for me. I watch a lot of documentaries on Netflix and to be able to go through them (especially the slow ones) at 2x the speed is fantastic.
Works flawlessly and a seriously great way to support PiPifier. Nice work.

Unaccessible
By catherinerenes (Pcmac user)
DID NOT WORK
After reading previous reviews, it seems to be a common consensus that this app does not show up in the extensions tab and therefore useless and a waste of $2. NEVER had this issue with a product before and got no feedback from customer support.

I can’t get it to work
By EricNordGreenville (Pcmac user)
I’d be happy to pay $2 for this if it worked, but having payed $2 for an app that doesn’t work, I’m not happy with it. I installed the app but the extnesion does not show up in Safari. I emailed the developer but have not heard back. Waste of $2 so far.

Doesn't work.
By Herolint (Pcmac user)
There's nothing more to say. The plugin simply doesn't work.
