Compared to other mice Logitech has released, the G900 is actually pretty tame, other than the section where the buttons hinge, it's really incredibly plain for such a high end mouse, much less a high end Logitech gaming mouse.
Turn off the light, and place it on a black mouse pad and it practically disappears, something I joked about in my
review of it. Pictures (for once), because of lighting, actually make it look more wild than it actually is, for example the striations on the bottom are barely visible to the naked eye, and the dark gray area in front is made darker because of overhead lighting. As the shine wears off, the details blend even more.
This is how you see it in pictures, note the tons of small details visible.
This is more how it actually looks to the naked eye. All those minor details vanish.
Anyhow, if you want wireless...
First thing you should do is go look at Logitech's website for mice (gaming mice in particular) because they have dominated wireless mice for the last 20+ years, they should be the first (and possibly the only) place you should look. There are other companies, but none of them have the experience of Logitech. I have bought MANY wireless mice over the years trying to find alternatives to the pricey Logitech, I've probably had more wireless Logitech mice than most GH users have had mice, but they all were garbage by comparison, disconnects, short lifespan, lag... A $20 Logitech tends to be more reliable than most other companies high end mice, which is pretty sad when you think about it.
More importantly though...
Mouse, keyboard and monitors are actually the
most important aspect of your computer, despite what Intel and Apple want you to believe. I don't care how fast your system is, if you have a garbage mouse, keyboard or monitor it's going to be terrible to use, these are the things you directly interact with. Doesn't match your decor? You should re-evaluate your computing habits and maybe buy an Ipad. Sorry if that's harsh, but it's true. Its a tool, not a piece of art you hang on your wall. Sometimes it can be both, but sometimes sacrifices must be made.
My advice, if you want a great wireless mouse, get a G900 if you can swing it (look or wait for sales), they have been found for under $100.
