The sensor with cable and a metal bracket with three reflectors was delivered. A peaked cap did not belong with the delivery, just as a CD with drivers. The you have to download from the English-language site. Installation went smoothly, even here the menus entirely in English. In daylight, only limited use. A window is in the back of the user, the sensor is disturbed by the incident light so that it is completely useless. If you have an angle in front of or to the side, a window and a sunny day with cloudless sky, the rays of the sun can be so thrown by the three reflectors on the sensor obviously that occurs here very strong irritations. When used with a game you have to first open the program TrackIR and calibrated, then open the game program. Then you realize that you want to set different TrackIR, you must first complete the game, then log off the computer, then log in again to restart to TrackIR and then the game; at least I can no other way in Windows 7 to discover. If it works then it works well, even throughout several hours without failure. From a distance of 1.20 m (Hat reflectors - Sensor) he starts the up-rotation no longer reproduce very clean. For the current price of 148.- euros I would not buy it again, half the amount of money its value Währe appropriate.
