However, the Pyra has in my view a serious flaw: the driver of the mouse has no battery charge status indicator. However, the mouse will begin to flash when the batteries have reached their end.
A few minor problems that I have had more with the Pyra:
1. My Asus X52jk is a permanent high tone of itself when the wireless adapter is connected. It makes no difference whether I put the adapter into the USB hub or directly into the notebook. On my PC the sound is not heard and also when a game is started or a different power requesting application has disappeared the sound.
2. The Pyra will only work if you have Windows previously equipped with the driver. As with the Kone. So with standard USB input device driver is not working.
In spite of everything, I recommend every notebook owner who Pyra, because it is a real all-rounder!
