Love the blush nano ..very quiet and finally I can play games while the family is sleeping. The low profile and shorter travel also means that my hands are as tired from a long day of typing.
Need to learn to get accustom to the key placing as it is not the standard that I am used to. But I guess this is not a fault of the keyboard but rather personal preference.
The issuers is with the 2 keyboard lights on the top left and right. While online literature says that the left one can show when caplock is toggled, no matter how I configure, I cannot get it to show that. Had updated firmware as well and still can't configure that. I configured it to show the speed of keypress instead.
Finally the knob at the top right, It has the option to change to a narrow taller knob which is easier to turn with fat fingers, or the flatter wider knob. The taller knob feels wobbly and fragile, like you will break the knob if you apply too much strength. The wider flat knob however is slightly more difficult to turn with fat fingers because you can't exactly have a good grip around it.
So except for some of the minor cons described above, otherwise, pretty awesome keyboard.
