Buttons, Scroll Wheel

The main buttons are crisp and tactile, but have a fairly light tension to them. With all due honesty, they are a joy to press down, and there is no pre-travel or noticeable post travel either, which is absolutely great. The switches are Omron D2FC-F-7N models, which are rated for 20 million clicks.


The scroll wheel button is operated by a lower quality, square tactile switch. It's a bit stiffer than the main buttons, but is still easy and comfortable to use.


The scroll wheel encoder is made by Alps, which is a great addition since Alps is considered to be among the best in this area. Its scroll is light, but very tactile, and all 24 notches are well defined.


The CPI changer, located at the top of the shell, is bulging out, but I did not have any accidental clicks, though that depends on your hand's size and grip style a lot. The micro switch used here is a brand I am not familiar with, but its actuation force is fairly light, and it is quite spammable too. It feels nice overall.


True ambidextrous mice with side buttons on both sides usually suffer from one common problem, which is the positioning of these buttons. In order to keep them from actuating accidentally, the buttons need to be subtle and somewhat sunk into the shell, which leads to them being hard to access. The MX780 is no exception, and even though these side buttons have a very nice click-feel, they are still quite difficult to use for me. These switches have the same branding as the CPI changer, but their plungers are blue instead of red.

Cable

The cable is 1.8 meters long and has a braided surface. It's thick and rather heavy, and also way too stiff for my taste. This aspect could be improved because it generates a lot of resistance. On the bright side, it has pretty much no chance of braking. The USB connector is gold-plated and uses the USB 2.0 standard.

Mouse Feet

The stock feet could be quite good, but they have two main issues. The first being that they are not rounded down enough at their contact points, so they can scratch the mouse pad a bit, which causes unnecessary friction. The second problem is that the front of the mouse has a huge cable entry point, which is encased in a sharp-edged shell that appears to be made out out of aluminium. Drag the mouse in a certain angle and it can easily touch the mouse pad, which, again, causes a lot of scratching and friction. If you have some spare mouse feet, you can actually fix this by placing one on that front area.
