we think we know there are at this time 2 different types of vipers - perhaps a 50mhs and perhaps a 250 mhs - formally known as 90mhs and 18 mhs (?)
no today Comes the News that Shocks the whole customers - a part of it is Manual like a how to use - its opening as pdf-file but made with MS Office 2007
