Keyboard connects wirelessly from rpi to rpi as needed. Comes with a usb dongle that connects it wirelessly to the computer. Works on vizio smart tv with apps including youtube, netflix, and hulu. The tv comes with its own you tube app.

Not much bigger than a tv remote but very usable. Both products are very sturdy, and don't feel cheap. The keyboard is very lightweight and the perfect size for both of us.

The battery lasts a really long time, and is easily charged with a micro usb. The usb passthrough feature on the charger is a life saver as well.

The keyboard has an orientation sensor and adjusts the touch screen input. The trackpad works well, too. The volume controls work nicely. Even a trackpad.

Sending to sleep and waking up from this keyboard works only half way. On the replacement, the next day, the power switch is faulty. A hard reset is the only fix.

The trackpad on this thing is completely unusable. It misses clicks half the time, and the other half it clicks accidentally. Cursor moves on its own. Sometimes it works and sometimes your mouse pointer jumps around the screen.
