- They made anything above 2x speed paid.
- Thingolus Thingolus
- Forced to pay for a patreon after recent update
- SunVee
- became basically pay to use as the free version is practically useless now, it's limited to 2x speed as of a recent update and you have to pay for the ability to go up to 100x whereas it was up to 10x for free before, i wouldnt mind paying to do more than 10x but i'm very annoyed by the fact that such a good extension took the route of pretty much making the free locked behind a paywall. i will gladly edit this review to a higher rating (if possible, i dont review often here) if this is fixed, i loved this extension a lot before and am annoyed and disappointed.

- trash. stop cash milking everything
- Riley Brinson
- they changed it to be paid
- phương nguyễn duy
- Good use but why sudden a premium paywall? I've seen many greater dev who public enormous work just for free. Remember: you are not the only one who could speed up the browser, many other extensions could, and I could also use CE to speed up to 500x
- calihooya
- You ruined your own app, no one is gonna buy your patreon, "Speed Gear" is an extension that's better and free.
- ExplodIng_Andrey
- trash paywall, cracking it to remove the paywall. Also, if I find a way to exploit your website I'll be sure to deface it :)
- LIQUID 313
- terrible decision to put it behind a pay wall, uninstalling there is a chrome extension called speed gear that does the same thing but better, and without having to pay a ridiculous amount. I'm switching to that, I suggest you do the same
- heki
- i love it
- khronos PL
- limiting people to 2x? useless.

- I’ve enjoyed using this extension for quite a while, even though it could be a bit slow and laggy at times. The recent forced update, however, has left me disappointed: the only way to keep using the same features is now through a fairly pricey monthly subscription. I absolutely understand that ongoing development costs money, but a compulsory subscription feels heavy‑handed—especially for casual users who dip in only occasionally. Consider these alternatives: Let the legacy version live on. Leave the original (feature‑frozen) edition in the Web Store, then launch a separate “Pro” or “Premium” build with the new capabilities and subscription model. This keeps long‑time users happy, while still giving power‑users a path to support you. Offer a one‑time or lifetime licence. Many successful tools, such as Internet Download Manager, use a single up‑front payment that includes free updates and have thrived for years on that model Internet Download Manager Even a lifetime or “per‑major‑version” licence would give cost conscious users a fair option while still generating predictable revenue. Tiered pricing (including annual discounts). Even if subscriptions remain, introducing annual or multi year plans at a meaningful discount. Right now, the sudden paywall is driving a wave of negative reviews. I hope you’ll take this feedback on board, rethink the monetisation approach, and find a balance that sustains development without alienating your loyal user base.

- Era excelente. La máxima lentitud ahora solo es a la mitad de la velocidad standard. Enlentecer es por lo menos a la décima parte, como antes. Restablezcan 0.1 o menos. It was excellent. The maximum slow is now only half the standard speed. Slow down is at least one tenth as before. Reset 0.1 or less.
- Chill Chill
- liked it, please though add more precise speeds, i can only go intervals of 0.5x , please make it 0.1 or 0.05x
