Just fyi: i only have to charge the quad motes about every 2 years.
They stick to the backplate with magnets, so you can just pull it of the wall and put the usb charger in.
It has a press, long press, press release, and slide function (you can use any of the 4 buttons to start sliding, and the full mote is 100%, so you can actually dim pretty specific to, for instance 25%, by moving you finger to the middle of the lower buttons.
Its why i find these motes pretty handy.
Also, they keep pretty clean: no finger prints on them etc.
