This is the only keyboard that offers the multi device feature in this compact size. The keyboard saves the fn-lock state for each paired device. I even use it in fps games, it is very responsive and i don't feel much of any delay/latency.

Connecting to blue tooth is effortless. It supports both bluetooth and 2. Ghz and 2 bluetooth connections. It offers bluetooth 3. But i have no apple equipment, and my android equipment does not have usb a.

It is well designed and very solidly built. It does what it needs to well, feels nicely made, and has a clean look. The one complaint is that the nice-looking aluminum faceplate is not flat.

It is very easy to type on, has good tactile feedback and auditory as well. Typing easier than trying to do it with the xbox remote on the screen, which is time consuming and tedious.

No dumping now. It has dual keyboard markings. It uses 2 aa batteries (included) it takes two aaa batteries.
