Review title: Not satisfied
Product review: I had a need for an integrated keyboard & mouse with wireless so I tried this unit. I love the design. The keyboard has a great feel and is comfortable. It appears rugged and well built. After installing the (4) batteries (yikes) setup was a snap. Everything worked flawlessly, except for the trackball. This thing is nearly impossible to control precisely. It can take many tries before you finally land on the exact spot that you need to. There is no software control to adjust sensitivity. I thought I would get used to it but that didn't happen. I struggled using the trackball for over a week, then the keyboard went haywire. Certain groups of keys suddenly stopped working. In a way, I am kinda of glad this unit went bad because that will force me to replace it (with a different model). Otherwise, I may have just kept it and put up with hassle of operating the trackball.
