The main buttons are crisp and tactile, with medium tension. This puts them between an average Zowie and a newer Logitech mouse, as these are considered two endpoints for this matter. Some people prefer heavy clicks, some prefer light ones, and I would like the ones on the Kone AIMO if they would be a tad lighter. They have no pre travel or noticeable post travel, either, which is absolutely great. The switches are Omron D2FC-F-K models rated for 50 million clicks.
ROCCAT calls the scroll wheel a 4D Titan Wheel with above average scrolling resistance (still not as high as on most Zowie mice, though) and well-defined steps. The encoder is a green TTC. The middle click is operated by a darkish red (maroon?) stem TTC switch, which has a slightly higher tension than the main clicks, but can still be used comfortably. The reason of the 4D scroll wheel name is that it can be tilted sideways, giving you two extra buttons on this area. These switches are the same as the middle button's. In my opinion, this is a great feature if you need a lot of buttons because it's in a comfortable, easy-to-reach area. I did not encounter any misclicks it caused when I simply wanted to use the middle click, either.
A lot of mice have side buttons that are mediocre at best, but more likely bad because they usually tend to have a lot of pre-travel and bad quality switches. This is absolutely not the case here; the Kone AIMO is great in terms of this as well. The side buttons are light, don't have a lot of play, and feel very nice to press in. Oh, and we get three, not only two. The bottom one features the same dark red stem TTC switch as the middle click, while the other two have white stem ones.
We get not one, but two CPI buttons that can be remapped as well, of course, like every other button on the mouse. These are not in the way, so I didn't have any accidental actuations, yet they can be reached rather easily. They use the same switch as the upper two side buttons.
I also made a video in order to demonstrate how the buttons sound:
Cable
The cable is 1.8 meters long, and even though ROCCAT named it Flexi-Cable, I have seen some with cables that aren't nearly as stiff as this one. I would say it is absolutely okay with a bungee or if you tape it up somewhere.
Mouse Feet
I have to say I am quite disappointed with the feet of the Kone AIMO because they don't feel very smooth and make for quite a lot of friction on the mousepad. No other ROCCAT mice I have tested before had this issue. Since the weight is high, some faster skates would be much better for a better glide.
Disassembling
Four screws hold the two main parts of the shell together, which are located underneath the mouse feet. If you are planning on disassembling, be careful with the ribbon cable that connects the upper and lower circuit boards because they are quite easy to damage. The upper circuit board is held in place by two quite stubborn plastic clips, and I spent quite some time with getting it out. Unless you have a very specific reason I don't advise taking it apart. There is a reason this mouse has such a high build quality—parts that shouldn't be moving are affixed in place well.
