I have yet experience the rival
but Kana v2 performs very well in fps game but has a slight chance for misclick the side button
if you are a right handed better get the rival to avoid those situations

New baby in the house.. Ha3.. Eat maggi for the rest of the month..

rival for sure. im using it for couple of days now, quite nice

however the size is quite big and the clickers are kinda stiff.

so if u play a lot of clicking games, might be a little bit hassle

i bought from another forumer for 185 new unsealed.

hurm, if u have been using other types of ss mouse before, its the same size as sensei, but the shape is more ergonomic.

the clickers are a bit stiff but u can get use to that.

overall, i give it 9/10.

oh, it got customize colour as well. pretty nifty if u ask me

finally my SS Rival arrived.

   
compared to my previous CM Storm Inferno, the SS Rival is significantly longer but shorter at height. the weight is about the same. Rival's mouse click is stiffer but easy to adjust to and the noise is softer than the Inferno. there are two things to complain about the Rival. 1) that it doesn't come with braided cable; 2) the middle button only toggles CPI but there's no indication as to which CPI profile is currently in use.


the matte surface feels comfortable but it does attract a lot of fingerprints/oil/sweat and need constant clearning (wipe it with cloth after use)
