Replacement after about 7 years for Logitech G502 Proteus Core (first generation before the Hero sensor models). The G502 was great and still works, but it has a lot of wear and tear on the sliders underneath and Logitech especially saves on cables. It's braided, but it's lousy, it's hard, it's fraying and bending like a telephone handset cord, it's disgusting. But it still works. My even previous Logitech G5 had a better quality cable, I still have it and its cable is still as good as new. From what I've seen, even newer G502 models no longer have a braided cable at all. But back to Asuska. It feels just as good in the hand as the G502, I've only had it for a week, but I haven't had to get used to it at all. It just fits my hand, size wise it is similar to the G502. So whoever's G502 was small will have a small Keris II, whoever's G502 was big will have a big Keris II. But the extreme difference is in the weight. This is the first time I've had a mouse that weighs 54g and compared to the G502, which was 121g (without weights, with all five weights it was 139g, but I had them out), it's an incredible difference. The G502 is literally a brick in the hand against the Keris II. I didn't imagine it would be so noticeable. It rides smoothly on the pad, the buttons work perfectly, someone sometimes mentions that the side ones are smaller, but I don't have a single problem with them. The wheel also rolls very well. I bought it together with the Asus Scope II 96 keyboard, I tried Omni Reciever and it works without problems (connecting two wireless devices to one dongle), but I don't use it because the mouse then only goes to 1000Hz. Its maximum over dongl is 8000Hz, but that's after a firmware update. In the meantime, it can only do 4000Hz via dongl and you have to go to 8000Hz via cable. I have it set at the optimal 2000Hz for me. And frankly, I'm not able to tell the difference from 1000Hz and I don't want to drain the battery unnecessarily and put a strain on the CPU if I don't use it. As for the battery, after a week of use it shows me 76%, so I see about 20 days before I charge it, but that will be individual. Anyone who sits on it for 15 hours a day will probably run out of power a lot faster. The brightness on the wheel is set to 25% and I have it set in battery mode, i.e. the colour changes according to the charge from green to red. The quality of the workmanship is absolutely fine, nothing squeaks, the buttons and the wheel work nicely, the plastic is slightly rough, it doesn't slip and I play it nicely even without the grips glued on. With these I'm still debating whether or not to put them in, I've never had them In the package are the aforementioned grips, spare sliders and a beautifully braided soft power cable that is 300% better from the looks of it than on my G502. A lot of people swear at the Armoury Crate software, but I had no problem with it, it's in Czech, everything I needed I found and set up there, even the firmware update was fine. In addition, the mouse and keyboard remember the settings, so it is not a problem to turn off Armoury Crate and not use it, the battery status can be turned on in the windows tray without it. The sensor can go up to 42000dpi, but I have no idea if there is any game where you can set it that high and use it reasonably. I use 1750dpi in Windows and 8000dpi in games - GTA, DayZ, etc. I have no idea if in games like CS or Valorant you can set the mouse to use the sensor to its full potential, but I haven't found a game where I've been able to function at more than about 10000dpi. Related to that is the fact that the DPI button is on the bottom, which is about the only thing I would fault the mouse for, I'm used to the DPI button by the scroll wheel, which I find more practical. Especially with a gaming mouse, where gamers simply need to change the DPI continuously. I can't think of anything else to add to the mouse: -)
