I ordered both and just got them in. The sensei grip on the top is nice. I definitely can see it getting dirty though. It has plenty of grip. Although Im having some issues with the damn mouse. Whenever I boot up the software, it says plug in a steelseries engine device. Nothing will get it to recognize Im using the mouse.
Then the LCD on the bottom is constantly saying Upgrading v1.10. Whenever I left click to highlight some text the mouse cursor stands still, but I can still drag and highlight text. Its just hard to see what I am doing. Overall, its ok to me. I guess I WANT to like it much more than I do. Its a very elegant looking mouse but it seems more based for gamers who go to LANs and such. Im loving the Spawn ALOT more so far in just comfort.
I think your reading what Im saying wrong and vice versa. Anyway, thanks for the help with everything. G9x is nice but the Spawn feels a little better in my hand. I actually think its perfect for fingertip except the front left button is a tad rough to hit with that grip. The sensei is nice feeling but...well look above.
