Okay, I got the mouse. It is really comfy no matter what type of grip you use and the materials are great to the touch. All the buttons feel good and the wheel in particular is amazing. Extra wide is really nice, the ridges feel good, and it doesn't make noisy clicks but you still feel it. Resistance is just right and clicking it is clean. It also has a nice amount exposed in case you want to scroll a lot.
The mouse is a bit heavier than I expected, but it's not bad. The sensor seems to be doing perfectly well and the DPI switching works without a hitch. Any downsides are in the software. First off, when I launch the software, it resets my sensitivity setting for some reason. Then, it's just generally a bit unintuitive, and for some reason buttons 8 & 9 are flipped around on the main configuration but not in the listings for the tactics configuration.
As for what you can set up with it... pretty much anything. I mean really, anything you could possibly imagine, you can set it up to do with the press of a button, or a combination of buttons if you'd prefer it to be stuffed away a bit so you don't do it on accident. I'm also really glad to see that the rapid fire key can just be a normal key. Really, there is no reason for that feature in any game I can think of. BUT if you can, it's there.
That said, I have a general profile where I've mapped all the extra stuff to the keypad keys. That should allow any game to work well with it, and since the mouse is sending that signal, I don't even have to set it with the keyboard and hope I remembered the mouse button equivalent correctly. I'll probably create separate profiles for old games that can't be reconfigured like Wing Commander 4 and also one for image editing since it can do keyboard combinations.
If it starts crapping out on me I'll let you know, but the first impressions are pretty good aside from deciphering the software at the start.
