I bought the lamp end of April. Although it illuminates the keyboard. But I'm used to much better lamps. The USB connector is shaking violently back and forth. Thus, he has no real support in the laptop. That was also the reason why the plug today (06/07/2013) sparked the laptop and therefore the lamp fell to the ground. Of course, the diodes are broken and I can throw the lamp into the dustbin. Whether German diodes are more durable than those produced in China, but I can not judge. I'll buy now definitely a better lamp. Had I be tempted only by the name Ansmann this lamp to buy. Because the batteries of this company are absolute top.
