It's been a while since I last connected with Sairui. My first Sairui mouse was the Kinzu V3, a basic entry-level model. Though it had some resistance, the buttons felt stiff and tired my fingers after long sessions. Later, I moved into the Paint Master — and the results were pretty terrible (there’s a funny story behind that). But overall, I still felt good about Sairui. This time, I tried the Sensei 310, a new mid-range symmetric mouse. As someone who loves Dota 2, symmetry is my go-to. Let's open the box and see how this one performs — maybe even get a little lucky with some gold along the way.
Mouse out of the box:
Sairui's packaging hasn’t changed much over the years. The classic black and red combo is still there, just like the Rival 310. The front features a top-side rendering of the 310, with RGB lighting, split buttons, and the TrueMove 3 optical engine marked in the lower left corner.
The back of the package is pretty standard — multilingual descriptions as usual.
Inside the box, it's all about protection. I prefer the old flip-style packaging, which gives direct access to the mouse body.
The inner box uses a foam insert to keep the mouse secure. The accessories are minimal — just one instruction sheet. I remember they used to send stickers before, but now it's not included. Not sure if that's intentional or just a cost-cutting move.
Mouse details:
The Sensei 310 is a symmetric mouse with four side keys. Compared to right-handed ergonomic models, it's more flexible and ideal for MOBA games like Dota 2. According to Sairui, the 310 series has been optimized for size, but from what I can tell, the length is similar to the Sensei Master, while the width has increased slightly.
The surface is matte black, which is easy to clean and doesn’t show fingerprints. However, the texture feels rougher than skin-like materials. The sides are slightly tapered, making it easier to grip despite the wider build. The back design is bold and sturdy.
The right side also has two side keys.
Unlike the Sensei Master, the 310 uses split keys. The gap between the key and the shell is chamfered, giving a cleaner look.
The scroll wheel is made of soft rubber and feels smooth. The lighting effect is average, but the design is solid.
There are non-slip silicone wings for better grip. They feel more comfortable than the previous versions.
The left and right sides each have two side keys, totaling four. However, compared to the Rival 310, the side keys on the Sensei 310 are smaller, which might be less practical. For me, having four side keys feels a bit excessive — I never use the two on the right. I wonder if others actually make use of them.
The bottom of the mouse is simple, with three large Teflon feet. No extra details here.
The cable is a fine rubber cord, not gold-plated and without anti-magnetic rings. Still, it feels durable.
Features introduced:
The highlight of this model is the TrueMove 3 sensor. Sairui has used different sensors across its product line — the Rival 110 uses TrueMove 1, while the Rival 310 and Sensei 310 both use TrueMove 3. This sensor supports 100–1200 CPI, with 1:1 tracking at 100–3500 CPI. It also reduces jitter during high-speed movement, making it a strong performer.
From my personal experience, most high-end sensors offer more than what I need. As long as the mouse can handle 1600 DPI without frame loss and adapts well to fast movements, it’s sufficient for my gaming needs. Of course, this depends on the monitor I’m using. If you’re running a 5K display, 1600 DPI might not be enough. I tested the mouse on a furious beast pad at 800 and 1600 DPI, and it performed very smoothly. No straight-line correction, no lag, and consistent tracking.
Experience feelings:
Returning to the feel of the mouse. The Sensei 310 weighs 92.1g, which is relatively light. The split-button design offers consistent feedback, and the 50M switches feel familiar. The click strength is moderate, and the waist-to-waist design makes it easier to grip during MOBA gameplay. I love Dota 2, and the Sensei 310 delivers a great experience. However, in daily use, the smaller side keys aren’t as comfortable as the Rival 310.
As for the driver, there's not much to say — the Sensei 310 works with SteelSeries Engine 3, supports onboard memory, and is fully customizable.
The lighting effects are standard — just the tail logo and scroll wheel. Nothing too flashy.
To sum up:The Sensei 310 has a unique shape, no flashy lights, but it's simple and functional. Combined with the powerful TrueMove 3 sensor, it offers a great feel and performance. Based on my experience, the Sensei 310 is definitely worth considering. If you're waiting for a price drop, 399 RMB might be a good deal. After all, prices for mice can change quickly. Buy early and enjoy early, buy late and enjoy the benefits.
For FPS players, the Rival 310 is still the better choice due to its stability. But for MOBA lovers, the Sensei 310 is a clear winner. Even for non-gamers, the Rival 310 offers comfort and large side keys that are great for everyday use.
