- Ming Li (Magical452)
- It really helped make me to be more in control of when I take breaks because it makes it more difficult for me to get distracted. Unless you are actively trying to break it, it works just fine. I just wish it had more functionality such as ad blocking, but that's not it's main purpose, so it doesn't really matter.

- Nice minimalist UI, does block sites, either permanently or within focus period depending on your own settings. Great to have pomodoro integrated, but kind of not fully helpful when there's no notification of the start/end of a focus/break period. The block-by-word function also only applies permanently, but could have been incorporated into both the permanent settings tab and the focus period settings tab rather than having its own tab, so that we have the option. The one real bug is that the focus timer only lets you set the interval length by clicking the ± buttons, but not by typing although it looks like it does, which makes setting something like a 50/10 pomodoro difficult. This extension is really not that bad, but given all these nitpicks, I feel I can't give 4/5.

- I’ve been using this extension for a while now, and I have to say—it has completely transformed my browsing experience. From installation to daily use, everything about it feels smooth, reliable, and thoughtfully designed. The installation process was effortless; it added itself neatly to my browser without any unnecessary permissions or complications. What impressed me most was how lightweight it is—no lag, no crashes, and it doesn’t slow down my browsing at all. Functionality-wise, it delivers exactly what it promises, and in some cases, even more. The features are not only practical but also incredibly intuitive. The interface is clean, modern, and user-friendly, so even someone who’s not super tech-savvy would have no problem navigating it. Every button and option feels like it’s in the right place. Another big plus is how customizable it is. I can tweak the settings according to my personal preferences, which makes it feel less like a generic extension and more like a tool tailored just for me. It integrates seamlessly with Google services, which is a huge advantage if you’re already deep into the Google ecosystem. What I also appreciate is that the developers clearly pay attention to user feedback. Updates roll out regularly, fixing small bugs, improving stability, and sometimes adding new features. That kind of active support gives me confidence that this extension is here for the long run. In short, this extension is not just an “extra”—it’s become an essential part of how I use my browser every day. If you’re on the fence about downloading it, I highly recommend giving it a try. It’s free, efficient, safe, and genuinely useful. Honestly, I can’t imagine going back to browsing without it.
