Easy to use. You can pair this with many devices. I used this with my IPad. Works well, almost feels like a full size keyboard. The Pocket Universal keyboard delivers the same fast, natural typing experience you expect from any ZAGG keyboards. A unique design allows the Pocket Universal to fold into a simple 9in X 2.5in X .5in rectangle that slides into pockets and purses with ease. Strong magnets keep the Pocket Universal folded and help maintain battery life by automatically turning it off when closed. A built-in stand secures tablets and smartphones at an ideal viewing angle for simple use anywhere. I only used it a handful of times, so it has had very little use. I don't have the instruction manual this can easily be download. Downsizing, see other ads for smart pen, frames, rare books, book ends, and other cool stuff.
