Fig. 1 from top left to bottom right: Yellow LED keyboard, Logitech Optical Wheel Mouse, Travel Charger. Dark room, did not fire.

I hope the mouse is for most a helpful comparison clearly shows how unreasonable bright the LED is. Toddlers I would really not be as pure look. This is by far the brightest LED I've ever seen in my life outside of a flashlight and totally annoying !!
Wen is still interested: The device is fairly easy, probably without problems fits well in narrow outlets, the cable is good 1,3m long and delivers loud sticker 700 - 800mA at 5,0Volt.
But not with me. As payment I prefer more and reserves' my eyesight.
