Hello,
first, I registered here just because of this topic, so you can be sure I appreciate what you have done here.
Second, I own Cooler Master Storm Alcor and Roccat Kone Pure Military, for some time now, so I want to share my experience with them here.
I bought both of them, because of the sensor without acceleration, before I had Rocccat Kone for about 5 years.
CMSA:
- no software, just simple firmware files which you can load and that is, gentlemen, quite awesome, because no loading of software, no instalation. Each file changes dpi and polling rate and changes color of the logo, so you know, which is in use currently.
- it does not have rubber sides. It is all plastic, except of the wheel.
- bad thing is that main buttons are not a part of the body and sweat/dust/hair/whatever... can stuck and fall into the mouse between buttons and palm rest. And it also can't hold buttons up, so when you move your fingers up and down without click it can make noises just because of buttons falling onto the switches, but that is a detail.
- ergonomics are ok, not great and nothing really bad at the same time. No soft coating is plus for me, because it won't wear out.
- I am very sensitive to scroll wheel quality and this one is a real win for me, it has optimal resistance both in click and scrolling and still works and feels great after about half a year.
- buttons are optimal, nothing bad about them, just solid.
RKPM:
- software is slow with many unnecesary features, main negative is slow saving of settings to the mouse.
- in comparison to the classic roccat kone, this one is smaller. Length is still good, but last two fingers do not have enough space on the side, when I hold it I squeeze my hand a little too much. And you can't use dpi switch button on the fly, because they are simply too close to your palm. But overall shape is great, thumb buttons have good placement.
- simple design with just a few lines makes this mouse very easy to clean, which is really important for me and it was one of the reasons I decided for it.
- main negative for me is the scroll wheel. it has ok click resistance, a little more scroll resistance, but it already shows some weaknesses - when you scroll it all around, it doesn't match scroll point with position at one point and you have to move it for a few more degrees to make a scroll step. Little higher scroll resistance already made it little loose and when you scroll down, it tends to make clicky sound as it wiggles.
- all buttons are good, no weird sounds, all feel solid.
So If I compare them:
Both have good buttons.
Both are lighter than my old Roccat Kone even without any added weights in it.
RKPM has slightly better ergonomics, CMSA is bigger and thus more suitable for palm grip.
CMSA has better wheel.
CMSA has better software:-)
I hope, I have made a good picture of my experience with them. If anything is unclear to you, just tell me and I will try to reformulate or further explain.
