Title: Works great, but quality seems to be fading
Review: I've been using this keyboard and mouse for two years and I find it very comfortable and well designed.But after two years, it seems like the wireless is deteriorating. I have to move the USB base closer and closer to the mouse and keyboard. The only design flaw I found is the existence of the mouse wheel tilt clicks. I don't use these, but find that their existence makes the wheel click (which I do use) have a firmer resistance. A mild annoyance on an otherwise great product.
Is the review positive or negative?
