A while back, I got my hands on the G-Wolves HSK, and at first, it felt like more of a novelty than a serious contender. It was tiny — almost absurdly so — and I was curious how a mouse built for fingertip grip, with such a unique form factor, could influence precision aiming. But after some testing, it became clear: size and shape do matter, especially when it comes to fine-tuned control and rapid movements. G-Wolves weren’t just pushing the boundaries of design; they were challenging how we think about mouse performance.

Now, with the Hati R, they’ve refined that same approach. While still lightweight and compact, it has a more polished feel and is designed with performance rather than novelty. Let’s dive into the review, in which I will compare it to the HSK mouse in a few segments.

Shape and Design

The “V-shape” mouse, that’s how I’d call it. It leans toward ergonomics, with the right front side giving your ring and pinky fingers more room to rest — something that improves grip stability and was a common request from users coming from the HSK. Personally, though, I still preferred the tighter, more “pinched” feel of the HSK over this layout because this design choice was sometimes a bit uncomfortable to me, and I always had to adjust my grip for the very first minutes of gaming.

On the flip side, the left side — where the thumb rests — doesn’t quite hit the mark for me. The contour allows for a bit too much thumb movement, especially when reaching for the side buttons. There’s a slight wobble as I move my thumb back to its resting position, which can throw off my aim. In this area, the flatter sides of the HSK feel more locked in and consistent.

On the plus side, the flat base is a win — it makes it easier to swap out skates, although there’s limited room if you prefer larger ones. G-Wolves includes an extra set in the box, which is always appreciated.

I wish G-wolves had added a DPI button somewhere. As a person who changed DPI settings when switching games, I miss that feature. For now, I have to keep the web-based software open to do so. A bit annoying. They added a very small on/off switch underneath, though, something quite characteristic of the G-wolves brand.

The honeycomb pattern on the sides isn’t really to my taste — I would’ve preferred a clean, flat design. That said, I thought the indents might be annoying, but they haven’t bothered me in use. Still, they’re bound to trap dirt and sweat over time, which will make cleaning more of a chore. It also absorbs the modding clay, but more on that later.

The perforated coating is a nice addition that adds that “gold ball” or “strawberry” taste (if it’s red) to the overall aesthetics of the mouse, and I like it very much.

Bottom line? Very pretty mouse, nicely put together, but some of the choices may be controversial.

Coating and Weight

I initially said in my unboxing video that the coating is great. It’s not entirely true after putting hours into testing the mouse. Fortunately, the coating is perforated like a gold ball, which adds additional grip to the mouse. But I’m afraid that if G-Wolves hadn’t used that, my experience would be different, as I see that this coating is far from perfect, and the mouse could slip out of hand, and with such a small mouse, the coating is very important.

Such a small mouse can’t be heavy, and G-wolves know how to do it — the mouse weighs around 28–29 grams (depending on skates), it is very well balanced, and you feel it’s like a feather, absolutely effortless to use. Due to its weight, this mouse is not the best choice for slow, tactical FPS games.

Bottom line? The coating could be better, weight is appropriate for such a tiny mouse.

Build Quality

I know that previously, G-Wolves had some QC issues and some mediocre build quality due to innovation in the weight and overall mouse design. But it seems that those times are long gone now.

Pressing on various parts of the shell (also on the honeycomb sides) yields no creaking, no flex, and no unwanted noise — it’s tight and well put together. Despite weighing in at just 29 grams on my scale, the G-Wolves Hati R 8K doesn’t feel delicate or flimsy in the slightest. On the contrary, its construction is surprisingly robust for something so ultralight. I don’t know how, but they managed to cover all areas of a well-built product, with no rattling, creaking, wobbling, or flex.

Bottom line? Excellent build quality, QC issues are now gone.

Clicks and Buttons

The main mechanical switches/buttons have a sharp, satisfying click with just the right amount of movement before and after actuation. They bounce back quickly, which makes rapid clicking easy and comfortable. They work perfectly in-game for me. Also, the slight inward curve helps your fingers settle naturally into place. There is a bit of side-to-side play in the buttons, but it doesn’t affect performance or feel during use because it’s minimal.

The scroll wheel is also well-balanced. The steps are well pre-defined, the click is not too heavy to my liking, and it is pretty silent too.

The side buttons are also pretty crisp (no mushiness), sit a bit too far back for my liking — especially the rear one — which can make them a bit of a stretch if you hold the mouse closer to the front. Also, they are too small for me, and I wish G-wolved had made them bigger, even if that would have tinkered with the overall looks of the mouse. That said, they click cleanly, with almost no give before activation and a firm stop afterward.

They’re about the same size as those on the HSK Pro, which worked fine for me, but that mouse was smaller, and the side buttons didn’t curl into the side-back of the mouse. Ideally, they’d be slightly larger or placed a few millimeters forward here. But if you rarely use side buttons, it’s not something you’ll notice. Unfortunately, I use side buttons A LOT in all of my games, and my gameplay relies heavily on them. Hence, I struggled with them.

Bottom line? Crips, tactile, fast — the clicks are great. Side buttons will not be a problem if you don’t use them too often.

Software and Battery Life

The browser-based software is a great addition — it’s convenient and easy to access. The G-wolves software is one of my favourites, actually — it is very well organized, works fast, and the UI is also intuitive to me. There’s huge progress in the last 2 years. Unfortunately, I had to go to the web software every time I wanted to switch DPI, but that’s the design fault of the mouse, not the software itself.

Moreover, G-wolves has just released their software version for… mobile. Yes, users can use their phones to scan NFC tags to quickly switch mouse settings. They can also switch to the mouse settings used by your idols. That’s how innovation should look like and G-wolves lead the pack.

Battery performance (250 mAh unit) has been pretty solid, especially since I’ve had it running at 4,000Hz polling the whole time. I gave it a full charge right out of the box, played heavily at least 8 hours a day, and I lasted for around 2 days, totalling around 20 hrs. The use of mechanical switches instead of optical ones probably helps stretch out the battery life a bit.

Bottom line? Acceptable battery life, very good web software.

Modding Clay

I have tried out the clay provided in the box by G-Wolves to shape my Hati R slightly differently. The material is not sticky to your hand, which is a good thing and would probably come off easily whenever you wanted to get rid of it. It has its smell, though, but what would you expect?

You don’t have to worry about modeling it beforehand because it will naturally shape down when you put your hand over it.

I was just a bit worried if putting it on the honeycomb sides was a good idea (notice how it pierced through), but I managed to scrape it off with a needle and some effort. Fortunately, nothing went inside for good, and a little shake cleared things off.

It is a very good idea in general to provide users with this alternative. After all, we’ve been looking for the endgame, and this little mod can bring us closer to finding our own Holy Grail. Thank you, G-Wolves, for being innovative!

Bottom line? Innovative idea, be careful when applying to the honeycomb design, though.

Performance

Let’s put it this way — If I didn’t have to use the side button and the scroll wheel so much, I know that I would have switched to this type of mouse for good. (HSK also didn’t stick with me due to the scroll wheel.) I am a gamer who uses side buttons/scroll wheel all of the time, and I don’t want to change my gaming config at this moment, and the side buttons’ placement mostly made my gameplay unsatisfactory. However, for those who can firmly keep the grip, this mouse can be revolutionary. The ease of micro-adjustment, the overall tracking, and how easy you can switch targets with such a mouse is astonishing. I think that the HSK mouse can even be better at that, but this one is also Premier League for this.

Initially, I was overshooting targets because my muscle memory was putting up a fight, but I switched to a control pad (Ninjutso NPC Pro) and it was much better. So, you should also give it time, it will pay off — do not throw the mouse away after a few days, it takes time to adjust.

When it comes to the sensor, Pixart 3395 performs great here, and its implementation is very solid. No problems with LOD, no cut-offs, no spin-outs, responsiveness is great, and the overall click latency with the mechanical switches used here is very low too, in all polling rates. I’d suggest using 4k if you want higher polling rates, though, because it’s the most stable and reliable one of all higher polling rates on Hati R 8k. Also, Motion Sync adds around 0.5ms to latency, so keep that in mind. The overall latency is spending, absolute industry top around 0.3 ms (8k polling) and 0.5 ms (4k polling).

However, I have noticed that after lift-off, the next click will have significant latency added to it, around 16ms. That was probably a defect in the anti-slam solution applied to this mouse.

Bottom line? One of the best fingertip mice, but not entirely for my use case. It performs great but has some added latency after lift-off.

Summary

The HTR 8K mouse sits on the premium end, and it isn’t a mainstream product; and it’s clear G-Wolves wasn’t aiming for mass appeal. Within its niche, though, it brings a lot to the table that sets it apart from similarly priced options. It wasn’t for me, though, due to the reasons I’ve mentioned in the previous sections.

But it is a fingertip mouse for gamers who like to innovate, look for something else to try in their setups, look for the Endgame Holy Grail, or just want to become better at aiming. Because aiming with smaller and lighter mice is generally proven to be more efficient, the thing is to find out that sweet spot between balance and dimensions while still gripping the mouse in the most aimed-centered method.

While it has a few minor flaws, the Hati R 8k delivers where it counts: great shape for fingertip users, crisp button response, solid performance, and surprisingly sturdy build quality given its ultralight design.

All in all, if you’re already a fingertip gripper — or seriously planning to make the switch — this mouse is well worth a look. But if you favor a claw or palm grip, it’s probably not the right fit unless you’re just curious and don’t mind spending for the experience. Also, if your games are slow and tactical, look somewhere else. If your games are fast-paced and involve a lot of target-switching and tracking scenarios, and you don’t need to use side buttons too often, this could be the one.

Bottom line? If you’re a fingertip user, you must try this mouse.
