SteelSeries Sensei 310 Gaming Mouse - 12,000 CPI TrueMove3 Optical Sensor - Ambidextrous Design - Split-Trigger Buttons - RGB Lighting, Black

Good mouse for $37 but after about 1 year the adhesion of the grey pads on the sides starts to fail and the pads slip. The glue material also leaks out. I fixed this by removing the pads and all the glue material and using gorilla glue gel to adhere the pads. Should get plenty more use out of the mouse now.

The mouse is solid for the price. Im right handed, and wouldnt of purchased the mouse had I known it was ambidextrous. There are side buttons on the right that are annoying and easy to accidently hit with normal use.

Lots of reasons to like this mouse. Its sized well for larger hands, and is ergonomically satisfying. The build quality and button action/feedback are great. The sensor has been very reliable. I think the sensor tracks great when playing fast fps, my mechanical skills have increased with the purchase of the 310. So far my favorite part of this mouse is the sensor reliability, it has never lost its mind and swung my view to the sky and stuck me there when putting the mouse through its paces, like in close quarter combat. Other mice failed in those situations, this one never has, even when Ive fooled around and tried to make it fail. Im pleased with this mouse for FPS and dont see a need to spend more money on a better mouse when this one seems to provide all the performance I need.

Sensei 310 is an excellent ambi mouse. Love the silicone side grips, probably one of the most comfortable mice Ive used so far. Im on the fence on whether this will replace my fk2 as my main gaming mouse, this mouse is comfortable! Honestly I was suprised due to how low of profile this mouse has. The sensor is excellent quality with precise 1:1 tracking for FPS (tournament grade). Can definitely use this for many different game genres. Great for someone who wants a nice mouse thats not too flashy but hits a home run in performance. 2 RGB lighting zones, very aesthetically pleasing. The SteelSeries software is easy to install and use. It has a matte black finish with really crisp feeling LMB RMB clicks. My only gripe is that I wish the scroll wheel was tighter, not as much resistance that I was hoping for. Im sure it will be good for web surfing and document browsing but for gaming functionality a little more resistance wouldve been nice. The triggers are split on this mouse with omron mech switches which apparently boasts a 50 million click guarantee. 2 buttons on the left side of the mouse along with 2 buttons on the right side of the mouse. They are thin enough and placed well to avoid accidental key press, could be a tad larger in size but still very well done. Since I just received this mouse and started using it I cannot comment yet on the durability of this mouse but from a short hand experience the build quality is good so my expectations of a good length of life is there for me. Definitely feels like it will last longer physically then the rival 300 series I was previously using as the grips on the sides wore down incredibly fast leaving the mouse to have a very battle scarred look. Quick deterioration = change of shape = inconsistency in grip (IMO). Hopefully the silicone grips do the trick. Note this mouse is pretty light, great for some but not for all. Definitely doesnt hinder the feel of quality to me. Highly recommend this mouse, especially for all you competitive players out there. Great job SteelSeries, new favorite mouse added to my collection (replaced the rival series for me).

For all the features mice have these days, picking the right shape is still paramount. My grip is primarily a fingertip grip, but I like to rest the bridge of my knuckles on the body. The Rival is perfect for this style. The 310 appears a bit cheap, but the plastic is porous, resisting finger grime, and the rubber sides ensure a firm grip in all circumstances. There are lighter mice on the market, but the Rival is the right weight for me. Lighter mice led to fatigue over time due to the fine motor skill required for small movements. Click weight is good and the side buttons are big, making them difficult to miss, though I wish the center-mouse-wheel click required more force to actuate. I adjusted but, as is, it requires barely more than the weight of a finger to press. I was impressed by the SteelSeries software as it prompted me to disable mouse acceleration in Windows. The software allows you to adjust the two sensitivity (CPI) set-points, button mapping, acceleration/deceleration, angle snapping, and polling rate before saving it to the mouse. Frankly, its more than I need, but it allowed me to dial in my sensitivity precisely and experiment with the mouse acceleration. Though the linear 1:1 tracking felt great, I found mouse acceleration was required for me to get from edge to edge of my 21:9 ultrawide without lifting the mouse.

I dont play games daily, just need a quality mouse with high pointer precision AND ambidextrous design. I have to swtich hand as years of using mouse on right arm is causing RSI on every joints in the arm, the worst is shoulder. Only have it for a few hours, construction is good, at least comparable to Logitech G402. Side buttons are not on the same level as the mains though. All buttons are programmable, but I could only use the preset command, eg, when trying to record ALT+F4 as key setting, it immediately close. Logitech and Microsoft can intercept and record this command. It does have Windows preset to close application but direct keyboard command has higher priority than OSs. The shape is like the early Microsoft Intellimouse Optical Mouse, a mouse(multiple units) I used for nearly 10 years until it get phase out. I heard the original Sensei was made to imitate the Intellimouse Optical Mouse. Being the user for nearly 10 years, I find the Sensei 310 to be wider but lower in height. Would have prefer the originals shape as it would be more comfortable for web browsing and leisure uses with palm grip. If you are looking for ambidextrous mouse with sensible price for everyday uses and casual gaming, this is highly recommended.

Doesnt have the frills of some of the fancier gaming mice, but if you just need a few extra buttons, this is a good pick. I like it much more than the Logitech G502 Hero it replaced. Its lightweight and isnt adjustable, so if you want a heavier mouse or one with weights, look elsewhere. I prefer the lighter weight.

Have had it for three years and has been a really good mouse! Still going strong

I absolutely adore this mouse. I was skeptical about the triggers based on the screenshots, but they feel really nice. The sensor feels amazing and this is coming from a Razer Deathadder 2014 edition. The mouse is very light as well. I play all types of games with this mouse, but this mouse would definitely be most suited for first person shooters. The shape is very nice. One thing that could turn people off is the material of the device. To keep the device so light, Steelseries had to use a mostly plastic construction. As a result, this thing feels cheaply built. The plastic does feel nice though, its smooth on the top and has grippy rubber pads on the sides. It does not come with a gold plated USB unfortunately. While it doesnt do much, it does allow the port to last longer through multiple insertions since gold is malleable. The cable is also a light, thin non-braided cable. Its very weightless and it might not be for everyone, but I do not mind. Steelseries Engine seems to be decent software, you can adjust many settings for the mouse.

Any mouse at this price range from a reputable manufacturer will have the sameish mid-high tier sensors. This comes down to feel and shape. Everything not mentioned consider excellent. Hand size: Large (18x10cm) | Grip: Fingertip - Shape is ergo with a low bump in the mid-rear left side - A great in-between shape of ergo and ambidextrous - Unique pearish shape, truly the highlight of the mouse; slightly flat narrow front, slightly wide ergo rear - Unbelievable casual comfort and precise aim control - Rubber grips! I like them - Shell is NOT butter smooth or slippery, it is a near perfect textured surface A great mouse for Medium or Large hands and Palm or Fingertip grips; an absolute must buy if you are fingertip with large hands
