Summary: I got this mouse particularly because its ambidextrous. It had good reviews on amazon compared to the other similar mice I was comparing. People were reporting no issues, so obviously I decided on getting a reliable mouse. Indeed it was a solid mouse until it messed up my browsing and most importantly my gaming experience, where precision is key. That started after a couple of months of moderate usage (~6 months).
Summary: Like i said, I got this to replace my Razor Diamondbacks which have been discontinued. I have tried several different mice, but none of them felt as comfortable as this one. The mouse contains white LED's and will initially do a slow pulse, but can be steady or disabled in the software that comes with the mouse and even has different brightness levels. Overall this is an excellent mouse, and the easy to use software and drivers have worked flawlessly for me.
Pros: Ever since Razor had discontinued the Diamondback, I've been looking for a mouse to replace it. After doing some research, measuring, and trial & error, I finally found the perfect mouse to replace my beloved Diamondbacks. The SteelSeries Sensei, which is almost identical in size, has the same side buttons, excellent rubberized grip that makes it easy to pick up and move, and as an added bonus has a profile button by the scroll wheel to instantly change the DPI. If yo...
Cons: The only issue I've had is that the rubber grip on the thumb side had developed some very tiny cracks in it within just a couple of months. Then after a few more months the same piece developed a slightly burned/melted spot near the same spot, but not directly under the thumb. Not sure what causes this, but rest assured that it does not effect the usability of the mouse nor is it noticeable save for when you closely examine the mouse. Because this issue does not affec...
Summary: I was looking for a replacement of my classic and beloved Microsoft Optical Wheel Mouse. I am a developer and gamer so the mouse needs to be responsive, precise, fit well in my hand, and easy to quickly lift and reposition. From my research this mouse is the closest you can get to the original Microsoft Wheel mouse which is hard to find new these days. Overall this is decent replacement.
Summary: Considering returning this because of how uncomfortable the mouse is. Then again this is the best wireless mouse out there and it's very comfortable to just take this mouse to my bed.
Pros: Every pro is advertised.
Cons: Plastic. They should have used metal for a 160 dollar mouse. There are computers (not good ones) cheaper than this. Charging port could have been designed to hold the mouse a bit better. I have to press on the mouse to make sure it's charging sometimes. Ambidextrous. at 160 dollars a mouse, they should make one for right hands and a separate mouse for left hands. The fact that they made it ambidextrous makes it much more uncomfortable compared to the mionix naos serie...
Summary: For this price point I expected more and being designed in scandinavia, my old knockoff gamer mouse felt more solid. Returning this, the mouse wheel is driving me nuts.
Pros: Light, very good click response and the main buttons. Very good precision.
Cons: I'm surprised not many people have mentioned this, but the scroll wheel is extremely flimsy. It's not responsive and it shakes sideways. Also, I'm not sure if it's my hand, but I end up clicking the buttons on the right side accidentally all the time.
Way too light and slim design makes it no good for gaming

Summary: Way too light and slim design makes it no good for gaming. This is my first and last steelseries mouse. Overall the mouse feels like a quality product and potentially good for other activities besides gaming but since they pegged it as a gaming mouse, it gives me no level of confidence in their designers.
Pros: This mouse is great. It is not the heaviest mouse in the world so if you like the hefty mouses this is not the one for you. The mouse is very customization and you will never get bored making new profiles with all the colors to choose from. It has a very good sensor and I have not yet feel if not track.
Great grip feel, very light, but essentially three buttons

Summary: The Sensei is the lightest mouse I've used in a while at 90g, so its lower starting friction and momentum make it easy to use with a fingertip grip. The wheel is fairly stiff, with well defined detents that makes selection very easy, and the middle button has a tactile-enough click to be useful, if not anything special.
