Summary: Comfortable hold, but center sensitivity button requires some getting used to. Scroll wheel will get stuck and involuntarily execute from time to time. However, the biggest problem with this mouse is its left-click lifetime, which is incredibly short.
Summary: Definitely not worth a $60 price-tag. Would probably buy for $20.
Pros: Ok for left hand users. One large button on each side.
Cons: Short lifetime. Bought this for $30 on sale. After around 2 months, the inner black rubber wire started tearing out of the threaded wire casing. After 7 months, it started to die, and if the wire was moved too much, it would disconnect. After 8 months it was unusable. the mouse would only connect...
Summary: This is a great mouse (in fact, i liked the one i had at home so much i bought one for the office too), but alas, it was temporary. The middle mouse button on both have started to give out now, not initiating when it should.
Summary: I've owned this mouse for almost exactly a year now and, incidentally, for about the past year I thought I'd found the perfect mouse. The shape, size, weight, side button placement, material used and just the overall feel are pretty much perfect on this mouse.
Summary: I bought the Kana back in June of 2012 and was a very good mouse to use. I had a claw-grip with it, and the shape of the mouse is absolutely perfect for it (at least for my hands they were). Up until recently, I decided to switch to palm grip and it is still comfortable to use.
Summary: Good + The looks + Design + Grip + Lightweight Bad + Sensor not that good, compared to the G400 or the Deathadder 3.5 + Only fixed steps of DPI (3200, 1600, 800, 400) + Not onboard memory My opinion is that this mouse is better for general use that for gaming, there are a lot of better mice around.
Summary: I got this after having owned a Kinzu for about a year because I needed more customization than the Kinzu afforded me. Unfortunately, this mouse and I never really clicked (GET IT?!). It's a nice size, but I use a fingertip grip and this mouse is a tad bigger than I would like with my grip.
