Almost all the shortcomings are related only to the software of this mouse, there are no complaints about the hardware, especially considering the cost of the mouse (I bought it for ~ 900). The mouse works fine, the sensor moves the cursor without jerks or any other bugs. I hope that in the future the developers will ate the software and fix the things that I indicated in the shortcomings, then there will be no price for it at all! I recommend it to gamers and creative people who need a large number of programmable keys for work.
