Pros Caps lock indicator ... that's it.
Cons Within 15 minutes the keyboard was dead. Had to unplug and reinsert the USB dongle to get it working again. Mouse motion is EXTREMELY erratic, with multiple freezes. HATE the scroll wheel on this thing ... VERY mushy ... no feedback!
Summary This replaces a two year old, low end wireless combo from Logitech. The functionality of special functions on the keyboard takes a step backwards. Other keyboards (including my old Logitech) used one key to start programs, such as opening email; this keyboard requires using two keys ... Function key plus the other key. Logitech hypes the 2.4 GHz output but the erratic motion of the mouse (I'm assuming it's a communications issue with the dongle) makes this combo good for nothing but a paper weight.
Basically Logitech has a ZERO with this combo, IMO. This one is going right back to the store.
