The keyboard itself is made of black (or optional white) plastic, but it looks quite stable. Ergonomics and button layout is standard for flat keyboards, back to the keyboard can be superscript. Key resistance and pressure point are a bit strange at first, especially if you are otherwise rather works with Cherry keyboards or notebook keyboard. This keyboard has to be a little stronger tap when writing; for friends quite smoothly operating keys of this keyboard is nothing more.
Bluetooth is always handy when you want to use a keyboard with the tablet or a large smartphone. Office suites are available for these devices, too, in many Tablets they are already pre-installed. I use, for example on the Galaxy Tab the Wacom Office for writing, save in Dropbox and can then continue working on the PC. Similar solutions are also available in the iOS world. For all devices can I use this keyboard; connect to Android and Windows PC via Bluetooth dongle works smoothly, as the switching of the target devices on the keyboard.
When I had my first tablet, I have tried to write on the touch screen also times longer texts, but that quickly gave up in exasperation. Without a keyboard writing is not fun, is inaccurate and takes so I use the road a small Bluetooth keyboard. Now at home I like to grab this keyboard here. A proper, big keyboard as on the PC. Since I have the keyboard now here am even gone over to join them via Bluetooth with my notebook in order to sit a bit further away from the screen can. The whole without changing plugs anything or having to make me worry about compatibility. Great.
The keyboard is thus directed clearly at users who want to use multiple devices so as smartphone, tablet, compatible smart TV and / or computer. Or to users who want to connect a device that can only be controlled via Bluetooth (integrated wireless keyboards need indeed at least one USB port on the device for the transmitter and the latter must also be supported).
Those looking for just a new keyboard for the PC, by the way is much cheaper without Bluetooth. Both with and without cable (wireless). This model would be oversized for it.
