Charging the uint from a USB port for initial use took about an hour. LEDs indicated when charged. The unit is very compact and light. It will fit in a shirt pocket very easily. When the USB dongle for the RF was plugged into my computer running Windows 7 it was recognized immediately so no drivers are needed. The keyboard/touchpad has a small on and off switch on the bottom of the unit. The instructions say it will operate 75 hours on the rechargable battery without the use of the LED backlight.
I was able to get 20 feet from my PC and it operated well. The only reason I did not check the full 30 foot range is I could not leave the room and still see if it was operating. There are 5 leds on the top of the unit hat show various operating conditions.
The touchpad is very smooth and will respond to a tap as the left mouse button. There are no multi finger functions at this time. The two large buttons underneath the touchpad are the mouse buttons. If the unit is not used for about 3 minutes it times out and the RF led flashes at a constant rate. A touch of any key for 1 second will bring it back.
In a darkened room you can turn on keyboard lighting for about 2 minutes with a double click of the RF key. The keyboard is easy to use for those used to smart phones and texting. If you have large hands and do not use small keys on your devices you may have a bit of a problem. The keyboard itself is layed out in a typical qwerty arrangement with modifications to fit all the keys in such a small space. There are no function keys available and the number keys and other symbols require the SF key to be pressed to select them. Led 5 lights up when the SF key is in use.
The unit would not look out of place in your media room or would be a great hidden keyboard to make changes to your MAME machine. It is small enough to hide inside a bartop or jukebox where full size keyboards are not an option.
