Update: Make sure your device has firmware 1.7 as it seems versions below that are a little buggy.
Very cool device. Wall mountable and looks great. Micro USB rechargeable with ability to configure:
When making configuration changes you can either a) wait for the device to wake up and have the changes sync over. The wake up interval for this device is 24 hours so if you are the impatient type you can b) press the button on the back for a few seconds. This will wake the device up and the lights on the front will blink orange. At this point the controller will send over its configuration changes.
Edit: Forgot to mention that each button supports push and held. So the dual actually has 4 possible button presses and the quad has 8.
