So now I could take the unit into operation and I can say, a super device. It har indeed taken it a bit, but I have already the 3rd Buch.Man it can operate easily, once you understand it a try. The battery is running very long. there are from today ie 4 weeks and I read a lot, am retired and it's still a bar übrig..Bin excited. He's a little bit difficult but that makes the device nichts.Also I can really recommend. 100% percent ..
