I am using a mechanical keyboard, and the backlight is either always on or constantly flickering. When connected via USB, the timing is not an issue, but there are many errors when using it wirelessly. However, isn't this product supposed to be wireless?!! I wish the backlight timing option could be fixed via firmware or software. I love this keyboard, but this issue frustrates me every time! It shouldn't be a difficult update, so I hope it can be addressed. I would really like to see a timer function for the backlight instead of relying on sensor activation!
