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

PROS: Nice balanced mouse that is left handed friendly. Buttons and scroll wheel feel good, mouse isn't too light. Tracks well with cloth or hard surfaced mouse pads.CONS: Only 2 DPI settings can be stored. Mouse cord sometimes catches on things. Software is decent but has a small learning curve.I am left handed so my choices for gaming mice is a lot smaller. For years I was using GSkill Ripjaws mouse. It's a good, ambidextrous mouse with various customization options like weight, grips and palm height adjustment. Software was decent. I did like that you could save up to 5 different profile settings in the mouse and that the cord is braided. The tracking sensor is laser so I definitely felt it tracked better on a hard surface mouse pad.I owned the Ripjaw MX780 mouse for a few years now and some of the buttons didn't always work, so I ordered a replacement via Amazon and ran across the Steelseries Sensei mouse. I read some of the reviews and decided to give it a go. I immediately noticed a vast improvement over the Ripjaw mouse.I am in the minority when it comes to weight. I prefer my gaming mice to be on the heavier side. Now the Sensei is not as heavy as the Ripjaw MX780, which with the added weights came in around 123g. The Sensei also isn't as light as other top rated mice, like the ones from Logitech. I did try a couple of the Logitech ones and they all were too light for my personal taste. I am left handed so the ambidextrous design is perfect for me. My hands are on the larger side. (measurements 22cm length x 14cm width) The Sensei was a good size for me. I also like that you can reprogram all 4 side buttons.I have 2 complaints about this mouse.1) I wish the cord was braided. I feel it sometimes sticks or easily catches on the surface of the mouse pad. I didn't have this problem with the GSkill Ripjaw MX780 mouse. Nothing a good mouse bungee could fix though.2) I wish the software/hardware would allow you to save more than just 2 DPI settings. My old Ripjaw mouse allowed to have up to 5 different profiles stored. The Sensei only supports 2. I play a bit of Overwatch and liked having different DPI sensitivity settings available to me for the various heroes in game.Overall the Sensei is a great ambidextrous mouse and I honestly prefer it as my main mouse and have replaced my other mouse with it.***UPDATE***I originally gave 4 out of 5 stars when I first reviewed this mouse and now, after 3 months of use, it's still going strong. No issues with the clicks and side buttons. The Sensei 310 still glides smoothly with the stock feet as it did the first day out of the box.

I got this mouse to replace a budget gaming mouse (Chinese brand) that I had been using for about a year. It was not a bad mouse, but I felt like treating myself to something nicer. This hit the sweet spot. It's got a great sensor, a very satisfying matte finish, very tactile buttons that rarely fire unintentionally, a nicely balanced scroll wheel, comfortable silicon side grips, and vivid RGB accents.The one con is the Steel Series Engine software for the mouse. It's not very intuitive and pretty buggy. Almost every time I have tried to change the colors I've had to relaunch the software after it failed to register my changes. The good news is that once you get your preferred DPI, macros, and color patterns set, you should be good to go. It even saves your settings onboard, so if you close the software or switch computers the mouse will keep your DPI and color profiles set. However, in my experience, you do need to open the software for some macros. I've set my mouse to control volume with the side triggers, which works with the software off. However, I also remapped the DPI button to open a program, which does not register with the software off. Not a huge deal, but worth noting if you're switching computers a lot or hate extra software.I've seen several reviews that view the light, plastic construction of the mouse as a con. I want to emphasize that this is NOT a con. The mouse does feel quite light and hollow - intentionally so. It's great for general use, but it's designed for e-sports and especially for first person shooters, where lighter is usually better. In this case, the weight of a mouse should not directly correspond with the dollar value of the mouse. There are plenty of cheap, heavy mice. Unlike a keyboard with an aluminum or steel back plate, there is no real benefit to a heavier, fortified mouse for gaming. Yes, the mouse is light and plastic - but this shouldn't be an issue if you don't throw it around and drop it. Even a metal mouse will break if you drop it more than a few times.Finally, I've seen complaints that the glue has begun to leak from the side grips. This does seem to be a real phenomenon that occurs with some of these mice. However, I have used this mouse for 5-10 hours a day for work and gaming over the last two months and have not had this issue. Perhaps this is more of an issue for people with more acidic perspiration, which could also contribute to the deterioration of the matte finish some have noted. For me, this has not been an issue. I will update my review if either of these things begin to occur.Final verdict: I got this mouse on sale for $35! For that price, it's unrivaled (get it?). At the MSRP of $59 it's more of a toss-up. There are a lot of good offerings in that price range. However, if you want a relatively light gaming mouse with a great sensor and you don't want to pay for some of the really expensive niche options out there, this is a great option. I can highly recommend it.
