Summary: I am very disappointed about this mouse.I had a Logitech G400, and it works pretty good for more than 2 years, after that I bought steelseries mouse because of the recommendation from my brother. HOWEVER, it is not comfortable at all compared to G400, and the right button started to be very insensitive after 4 month using it, it's not functioning anymore after a few weeks later.
Extremely buggy, here's my experience thus far including entire "support" history with Steel Series (Updated Yet Again)

Summary: I am actually rather exhausted from conveying all of the problems I have been experiencing with this mouse with Steel Series so I will simply include my entire support ticket exchange history with them: OS: Windows 7 Problem 1: Wireless Sensei periodically forgets or is incapable of executing macro commands, assigned buttons and randomly lags/disconnects.
Summary: I was reluctant to spend this much money for a mouse, but I figured that since it is something you use each and every day, why not splurge. So having said that, I had high expectations. Upon receiving the mouse it appeared to have a good build quality, and the braid wrapped around the cord was a nice touch; however, the unit I received had a serious issue. The switch for the right mouse button had zero spring to it, no tactile feedback of a click, and a hair trigger.
Summary: I'm not sure if it's because of the rubberized base, but this mouse constantly stutters at a subtle rate. You keep thinking you're pointing or hovering in the right direction, but it always shifts a few pixels shy of where it should be. I've read troubleshooting and settings for Windows 7 and nothing works. I put in a 5 dollar mouse and there's no problem. It's this mouse. 2 stars because it feels nice and no problems with LED, but it's way too frustrating right now.
Summary: A coworker ordered a Sensei and had it shipped to the office, as a replacement for one he had that broke. I knew the mouse must be good if he was replacing a faulty one with another of the same brand. Right? Wrong! Now that I've had this mouse for a year and a month and one of its main buttons is starting to fail, I realize that SteelSeries mice may just not be very durable. That's okay in a cheap mouse, but when paying an upwards of $70... it's aggravating.
Pros: Responsive. Precise. Programmable. Glossy.
Cons: Fragile main buttons! 70 bucks is too expensive for a mouse that will last 1 year.
Summary: I had a normal Sensei for over a year and loved it, but I wore out the main mouse button switch. I bought a Sensei Raw to replace it. I had my Sensei speed set to 450 counts per inch, but the Raw can only do 400 or 500 counts per inch. That was annoying but not a dealbreaker. I had a problem with this mouse's tracking. This mouse has little recessed hole for the sensor, and it must have trapped some dust. I blew it out a few times that problem was mostly taken care of.
Summary: I wouldn't buy this again. Was cheap on sale for $39, so not out that much cash. Pretty much only good for stock settings and RTS gaming.
Pros: Great feel, size, ergonomics. Braided cord and LEDs are pretty cool. Nice long USB 3.0 cord. Crazy fast CPI settings.
Cons: Limited custom ability. Unable to map browser forward/back to any other buttons other then 4/5. Limited support, no tutorials available for setting macros. SteelSeries support totally unresponsive to basic questions regarding mapping keys and macros. Macros fail to work in any game I've tried so far, so pretty much it's just good for the engine/cpi settings. However CPI settings are crazy beyond 1800 for FPS games...pretty much only good for RTS above 1800 (my persona...
