Excerpt: Mouse is fine. Keyboard goes quiet into power-saving mode. So if you hit a key on the KB after a while, it will be used only to wake the KB up and only subsequent key-strokes will be relevant.
Excerpt: I have had this keyboard now for about a week and it is making me work twice as long as normal. This keyboard does not type the keys that you hit and makes you have to double check your work constantly. This keyboard does not respond to key strokes and is constantly missing letters or spaces in sentences.
Summary: I bought it for work. I expected it to be litter better. I have at home one made by Windows for the same price, that performs little better. The keyboard is too light for me, and the mouse is too small. A heavier keyboard and a bigger mouse are just my personal preponderance.However, they work just fine and they are OK for the money.
Summary: This keyboard is very user friendly. Insert USB transmitter provided into your computer, insert battery into the mouse, turn mouse on, press "connect" button on the underside of the keyboard and...Voila! It's really that simple.
