The keyboard works well, and although I haven't used it long enough to test the battery life, the instructions were easy to follow. However, the print is quite small, so I suggest taking a picture of the instructions and zooming in if you have trouble reading small print. The keys are sensitive, so I sometimes type multiple letters accidentally, but I expect to get used to it over time. Overall, I love this little wonder. I wouldn't recommend it for people with larger fingers, though, as the keys are quite close together.
