I've owned many Lenovo (and IBM!) keyboards in the past and still swear by them. The reason for the 4/5 stars has more to do with the mouse than anything else. With my previous Lenovo keyboard (Ultraslim), the mouse was heftier and allowed for more precise, incremental movements. While the sensor on this one has a much higher dpi, this one is far too light is frustrating to use at times.
Keyboard is excellent, However mouse is bit disappointing.

Great keyboard and mouse. I use both for drawing with Autocad, they work well. The scroll wheel took a bit of adjusting for me compared to my old mouse, but it works well now that I'm used to it
