Main buttons are snappy and tactile, and without any significant pre-travel. There is some post-travel after actuation, but it's nothing serious. It generally feels nice to press and spam these buttons, which is great and also quite unexpected at this price point—definitely a nice surprise. The switches are Omron D2FC-F-7N models that are only rated for 10 million clicks.
Scrolling is light, but not too loose. It is rather tactile too, but I have seen better for sure. The encoder has a branding I do not recognize and is 9 mm tall.
The middle click is pretty good—it's not overly tight or too light, so accidental actuation should not occur. The switch is a green-plunger Huano model.
Side buttons are objectively impeccable; they don't have any unnecessary travel or play and are tactile and nicely spammable. The switches are blue-plunger Huano models.
The CPI/lighting button behind the scroll wheel is not in the way; while sunk pretty low, it is still well accessible. Its actuation is fine, though maybe a little mushy. It uses the same green Huano switch as the middle mouse button.
I also made a video in order to demonstrate how the buttons sound:
Mouse Feet
Mouse feet on this mouse are surprisingly good, although they needed some time to break in. They are very smooth and consistent and of medium friction. There are no replacements included in the package, but at this price point, I don't consider this a negative.
Cable
The GM11 cord is rather stiff and thick, not to mention that it could be lighter. It's definitely among the worse cables I've tried so far and needs to be fixed in place. I simply taped it to my desk, which had the mouse instantly became a lot more usable. The cable is 1.8 meters long, and the USB 2.0 connector is gold-plated.
Disassembling
Disassembling this mouse is very easy—all it takes is the removal of four Philips-head screws from underneath the mouse feet. There's some internal cabling, so be careful not to tear these as you open up the mouse.
