Is the Shape on the Bottom important for the sensor to work probably?
No, unless the lens is integrated into the bottom.
I think that would be your smallest difficulty, though... The buttons and scroll wheel might not line up or the PCB might not fit.... unless you're lucky.
You were right. I opened both mice, and the PCB is too fat to fit into the Razer Case, Mousebutton 5 & 6 are also impossible to install. The Sensor from the Logitech feels very accurate and precise but the Shape is just really uncomfortable to me especially the bumb right next to the RMB...
or a Zowie EC1 eVo since it's both better sensor and well, similar shape minus the weird bend in front - which IMO is better.
it's definitely worth checking out. a tad bit lighter too if that's of any interest. also steelseries rival but it's a bit different shape so might not be as suited to you.
Thanks for the recommendation. How can you know that the sensor of the Zowie is better? Ze Deathadder has a Avago ADNS s3988 inside while the Zowie runs with a Avago ADNS 3090, newer version should be better i guess
I might give the Zowie a shot, if its cheeper than the Deathadder. According to this guide
http://geekhack.org/index.php?topic=56240.0 the Rival has noticeable smoothing, so its out of the equation.
Ahh maybe i just stick with the G400. Many People say it has the Perfect Sensor, and to be honest the drivers are much better then from Razer.
