Perfect! Which a few annoying problems.

The mouse is awesome, no doubt. The material seems solid plastic and not rubber-coated, so it will last song. I didn't find the infinite scroll wheel of that much use, I prefer to use it in its regular mode. In regular mode, it has a lot of weight to it and it feels very robust, but its slightly harder to turn than that of a normal mouse. The software is wonderful, crashed on me only once, but hasn't done it again. The weight is something you won't need at all. The mouse if very precise and I can say that I feel NO lag in competitive gaming when using wireless mode. The battery lasts 30 hours and it needs maybe 3 hours to fully charge, which is perfect.
I dislike 2 things about it.
1. If you want to only take the mouse without its small plastic accessories box, you won't be able to do so, as there is no place on the mouse to store the wireless dongle. Which is ABSURD for such an expensive mouse. If you have good skills you can use a soldering iron to burn in a socket for the dongle. Do your research first so you don't ruin your mouse. Oh and also they could've used the port on the front of the mouse to easily attack the dongle, but they didn't.
2. A weird problem that I've had is that simply resting my hand on the mouse causes a right click. This doesn't happen for the left click. The right click is in no way defective or anything, it functions exactly as it should, but it seems like it requires SLIGHTLY less pressure to press, which causes my the weight of my finger to trigger it. This is also caused by the fact that the plastics that interact with the buttons are hanging and there's nothing around them to rest your finger on except the scroll wheel, so you have to rest it on the plastic which causes a click. I really hate this, a person with OSD will probably destroy the mouse in anger on the first day.
Note: The software has 2 modes - On-Board memory and Computer-Memory (called Automatic-Game-Detection) (for storing macros). For some weird reason, you cannot do macros that contain loops if you use On-Board memory. Some users have reported that they could do that in previous versions of the software, that feature seems to be removed now which is probably due to competitive gaming. Still, it's not something that would bother you if you use Automatic-Game-Detection.
Update: More than a year later, the mouse started double-clicking. Upon closer inspection, the buttons are well exposed to the elements, dust can contaminate them. The left and right button are well vulnerable to the elements. To fix my double-clicking issue, I used a can of compressed air to try and clean the button, which did not help. Instead, I turned the can upside down and froze it. That seemed to fix the problem. The mouse is very difficult to get into, and you risk damaging cables, batteries and housing if you attempt to do so. I noticed that a lot of other people are having the double-clicking issue, so keep that in mind. I would lower my rating to 3, but the mouse is just too great, even with a double clicking issue. They used an Omron switch for the left click, and Omron always deliver high quality, it's unfortunate they are failing on this mouse.
