I got me the unit bought a week ago, is inserted into the MAC and used. That's how it should be. Over the weekend at an event about 10 colleagues have used the laser pointer and all were released without explanation immediately very well with it. The possibility of the USB receiver stick accommodate the housing makes me happy. In addition, the device is switched off in this way and the battery can not be emptied by inadvertent pressure on one of the buttons (eg in your pocket). The unit has just the right size, is great in the hand and disturb hardly talk and gesticulate during free.
