The G-Wolves Fenrir Pro is a mouse I feel a lot of people know about at least in regards to reputation. This mouse is well spoken of in most circles especially for a fingertip mouse and is seen as sort of the recommendation you can just throw out there to anyone if they are asking for a mouse for fingertip grip, but why is that?

The G-Wolves Fenrir Pro is built upon a PAW3950 sensor and a Nordic nRF54L15 MCU with really fantastic implementation, the sensor feels extremely responsive and there is absolutely zero smoothing as expected with these modern sensors. What is more impressive with the Fenrir Pro is how stable everything is relative to other mice with similar combinations of components. The polling rate stability seems to be second to none from the brief tests I've ran on my unit even up to 8khz not really ever dropping any polls as long as you saturate the bandwith.

However sensor performance is really good on most mice nowadays, what isn't good on a lot of mice is build quality and click implementation. So how does the Fenrir Pro do in this regard? I'm happy to report that here it also does fantastic! My unit has no defects even after the use I've put it through, no creaking and even if I put pretty much my entire grip strenght into the sides of the mouse it doesn't flex at all since the sidewalls are supported by the PCB. The buttons still feel good there is maybe 0.1mm of pretravel and absolutely zero post travel which is really good. The low profile Omron D2LS-21 switches used also feel really good I actually prefer them greatly to a lot of the standard profile switches I have used in the past, they are no japanese omrons don't get me wrong but I'd easily pick these over the average Kailh or TTC alternatives and probably even Huano BSPDs(though I wouldn't pick them over Huano BSRDs as those are weighted a little more similar to a good batch of japanese omrons). The side buttons are also really fantastic on this mouse and funnily enough this is just about the only Fingertip mouse I have used where I can even access the side buttons comfortably in game, not that I use them anyhow since that inherently shifts my grip and thus my aim slightly.

Now to the things about the mouse that I would expect most people want to know about, the shape and also the weight, but let's start with the shape. This is 100% the reason why this mouse gets recommended so much and in all honesty, I personally have a hard time seeing the downsides here. For reference my hands are 20x11cm which is definetely on the larger side and for me at least mice like the G-Wolves HSK Pro and the Keychron M4 caused me some issues with comfort, especially when playing long sessions. This is not a problem in the slightest on the Fenrir Pro which I attribute to two factors, one being the fact that the mouse is obviously slightly wider than the other ones mentioned, but also the fact that at least in comparison to the HSK Pro, the sides don't taper nearly as quickly towards the front so it's a less agressive wedge shape and this means I don't strain my ring finger and pinky as much just to make sure that I have even a soft grip on the mouse. There is obviously a downside to the mouse being wider and that is that you lose some range of motion, and while I do lose a little bit I don't find that it affects the pen-like feel that I would describe those other mice as giving me. I think that might also come from the fact that the button height is so low, making me feel like I'm very close to the pad.

Now the weight! Is there really much to say here? I have personally always said that a mouse can't be too light, and this mouse really makes that more clear than ever. the Fenrir Pro clocks in at 19g on my unit with skates and if you haven't tried a mouse that is this light, I would highly recommend it, especially if you are on a glass pad. It makes every action feel like you have nothing in your hand, there is simply no inertia and stopping and starting motions feels so effortless, it honestly has made me feel like I can do things that I was not able to with other mice, especially in games like overwatch which has no acceleration on direction change. This sets the mouse apart in a way which I honestly feel no other mouse on the market can beat right now.

So is there any downside with this mouse? Yes, there is one and that is the scroll wheel. To be completely honest, I don't even find this to be an issue myself, but that is mainly because I learned everything on a 16 step zowie scroll wheel like 10 years ago. However, the scroll encoder is 12 steps and extremely tactile which is a bit of a weird choice on a mouse this light. I believe the reason for this choice is that they couldn't get any other encoders that are that short which makes a lot of sense, however it does make it really weird to use for a lot of people, especially in games like apex where movement options like walljumps are generally done with the scroll wheel or bunnyhopping in source titles for example. It is something you can get used to but I can't sit here and claim it is ideal.

In the end, is this mouse worth it's 160 dollar price tag? Well I would simply say yes it is. You get a mouse that is at the top of the line in terms of performance and one of the lowest weight options on the market. The shape is relatively safe, but doesn't sacrifice all to much to be safe at the same time. everything on it with maybe the exception of the scroll wheel feels fantastic. For me, this mouse gets a full five star score, and I'm extremely unlikely to swap off it in the near future. I highly suggest that you also buy one if it interests you, I promise that you won't regret it.
