Inside the G700s
There are four screws that hold all of this together, and since they are under the only set of feet you get, I wouldn't suggest opening it. Inside you can see that the top half has some of the buttons controlled with a PCB built-in while others need to press buttons on the top PCB on the right section of the mouse.
There are in fact a pair of Omron switches used for the right click and left click buttons only. This will give you up to 10 million keystrokes worth of life out of these two buttons and should ensure the G700s can spend a long time working on your desk.
Next to the Omron switches you can see a trio of the pad style switches used for the G button functionality. These are also used to record the tile movements of the scroll wheel assembly at the front of the G700s.
After pulling a pin and sliding the bar out of the way, I noticed that the entire scroll wheel assembly pops right out. It does make cleaning debris from it after a lot of use easier, but I think this design was used since the tactile scroll switch has now been moved to the top of the mouse, whereas before you had to flip the mouse to get that switch.
Removing the scroll wheel assembly did give me access to look at the laser sensor in the mouse, and here I found the Avago ADNS A9808 sitting on the lower PCB. I would have loved to look at the 16-bit processor and other bits, but the dual layer PCB construction wouldn't allow me to remove just one PCB out of the way.
Also, with the wheel out of the way, you can see the exact type of Omron switches used in the G700s, and as you can see they are the D2FC-F-7M with (20M) at the end denoting lifespan.
Due to not wanting to break anything, I did not remove the brown PCB from the top half of the mouse. With a flashlight I was able to see that the four left side buttons use similar pad type switches we saw in the lower half, just these switches have signal sent to the lower section via the 4-pin cable.
Now with the G700s all back together and fired up, you can definitely see the greenish lights on the side denoting a full charge. When it loses charge, you will get only two lights of amber for quite a while and at 25% charge one light will illuminate, but this time in red.
