The keyboard is fully charged yet ALL bluetooth buttons don't blink.  It just died over night, literally. The bluetooth manager does not discover the keyboard (tried it with several different computers).  Even a USB connection can not get the keyboard to work.  The keyboard is not old at all.  I got it on Amazon.de so I know the exact date of purchase.

As long as it was working, it worked great. The durability sucks.   I am not pleased that I have to throw away this device. More electronic junk for the landfill.
