Feels pretty damn good so far, not bad for R299.
They had another cougar mouse that was almost R600, so I'm assuming it's not exactly the cheapest brand. I don't need the higher DPI on the more expensive mouse though. Not sure if it had the same 3050 Optical sensor as this one though.
(P.S. I was surprised to see a R1500 Razer mouse at our tiny Matrix Warehouse, interesting, not gonna happen though)
It feels really good in the hands, claw grip and flat hand, so it's not too big coming from smaller mice like the MS mouse.
The button clicks require very little pressure which I love and they feel like really high quality, I guess that's why they keep punting the "Omrom Micro Switches" on the marketing material.
The underside has two of those big flat slippery panels front and rear for sliding on a surface, which I think is better than the usual four little standoffs on my other mouse (that's always getting crud stuck on one or two of them which has to be picked off using a fingernail). At least now if it gets cruddy the resistance increase on the underside of the mouse should be more gradual and linear.
The orange light can't change color. But I don't care. All things LED should die in my opinion.
It's heavier than my Microsoft mouse (about 1.5-1.8x) but it feels a bit better in the hand because of it and it doesn't feel like it's fighting the cable as much as a lighter mouse does. My MS mouse was maybe a bit too light, I realize that now.
The sides aren't rubberized, just a pattern grip in the plastic but I don't see that as an issue, unless maybe you don't wash your hands after fapping.
The optical sensor so far is as smooth as butter on the light desk surface in the picture. The MS mouse sometimes felt like it was a little jerky if the pattern underneath the mouse was on a weird part of the desk pattern.
It has four DPI settings, number two and three feels best (1500 & 2000DPI).
Two sides buttons, but I've never really gotten used to using side buttons. They feel nice though, I might have to start programming them properly and using them.
