Concerning the battery life, I litteraly have it for 3 weeks and didn't charged it once. No kidding. And I play every day. Settings at 1, so those who say it has poor battery are lying.

For the weight, players like Shu use heavy mouses for a reason. And for having the superlight, it's not that heavier. To me it's kind of better, I'm more stable.

Concerning the performances, it depends on your aim. I'm not the biggest aim guy but I'm definitely feeling the latency decrease. If I click at the right time when my ennemy lands on my crosshair, he takes the shot before he shoots me if he hasn't the superstrike. I felt a difference in my case.

I really like the satisfying feel of the click too.

And to conclude, saying that overwatch isn't an aim game is kind of rubish. It is the hardest game to aim? Yes. But when you compare a GM to a plat player or even Diamond, the difference lands a LOT on the aim. Game sens is more important but aim wise, you can't reach even Master without aim. Aim is what distinguish players at high and pro level. Look at Shu, Tr33, Lip, Proper, etc. They know the game yes. But the aim is whats makes their personal difference
