Okay so at the end of the day I have written a LOT more about the Sensei 310 and Rival 310 than I normally do. Part of that is because both mice have made a lot of changes though I did also spend more time than normal because of how familiar I am with the old Sensei and I had extremely high...

+ Silicone grip on the sides (must be cut in for the best feel) + Right and left mouse button separated from each other and the rest of the mouse (see image) + Very accurate sensor + Good sensor location "If you get very sweaty, the silicone crack can be slippery.

Some manufacturers work the concept of branding very carefully, with every product they release in a family maintaining evidence of physical continuity with its ancestors. Nearly all of the late Mad Catz's mice, for example, looked like mechas designed by Japanese animators. All of Samsung's Xpress consumer printers, like portable toasters that have evolved feet over time to chase smaller mammalian prey. If you liked the style of one Mad Catz RAT or Xpress printer you'd previously owned, chances are you'd feel reassured looking at others in the same lineage for potential purchases in the future. It felt like coming home. That's what branding is all about. Some companies, however, forego branding altogether—and yet a third group uses it as a catch-all. SteelSeries' Sensei mice would appear to fall into this last category. Among them are the Sensei 310 ($59.99) A glance at several products in the Sensei line—the original Sensei of 2011, the Sensei [RAW] of 2013, and the Sensei Wire...

We like the guts and the ambidextrous design of the Sensei 310, but a few advances in the configuration software would make this mouse something really special.

Shaped for lefties and righties alike; Attractive, solid design, yet light; Hair-trigger Omron switches and good optical sensor; Support for acceleration, deceleration, angle snapping

Only two DPI settings; No lift-distance control; Best for big hands; Non-braided cord; Ho-hum macro editor; Can't sync lighting for both light zones easily

I bought this because I wanted to replace my Razer Diamondback because the sensor kept stuttering which lead to my mouse jerking to the left or right randomly. Razer products are overpriced garbage. This mouse is great for the price and works extremely well. Its very responsive and feels comfortable in my hand. The Rival 310 was easy to set up and I've been using it for about 4 months now and it still works very well. 10/10 SteelSeries please just take my money!

The Steelseries Rival 310 is accurate (Truemove 3), extremely comfortable and accomodates most hand sizes and grip styles. The build quality is excellent and I could not detect any problems. It just looks and feels great. Coming in at 88.3 grams, the mouse is an excellent weight. Far lighter than the Logitech G502 and Corsair Glaive, both being over 120 grams. Sure, it might not seem that big of a deal at first. But after several hours, you feel the difference.

If you're a right handed gamer, look no further. This is the best mouse on the market right now, 10/10

For the first few months or so I've had no problems whatsoever but, now that it's seen a fair bit of use the rubber sides are barely being held on by the glue, and don't even get me started on trying to clean them without ripping them off on accident. The mouse wheel isn't as much of a worry as there's no chance of it coming out while cleaning it. The whole cleaning issue wouldn't exist if the sides had just been made as one part with the rest of the mouse. It's anybody's gu­ess why the mouse was made with removable sides, too late to complain now though. In conclusion, buy it if you want something to use in the meantime while you spend on other more important parts, but if you want something for the long term then I'd recommend spending an extra $30-$40.

The mouse is not bad , light and easy to use , VERY accurate in game. Only thing I could fault.. The price. With the launch of the new Rival 3 , the Rival 310 should be cheaper priced, the side grips fail & come lose from the mouse body, but even without the side grips it performs pretty well.
