And one star is too much for it!!! Very poor quality product, the cable included in the package is the worst - it overheats excessively, the pen does not charge at all. The reset button doesn't work at all, rendering the device useless. It is worth noting that although the device has the function to connect to a computer, it only supports very old operating systems (Windows Me, 2000, XP, Vista)! In short, even if the device worked as a hidden recording camera, there would be no way to view the recorded material. Wasted money!!!
