I have the predecessor, HD K 2, had and am very satisfied. The successor is a very successful development. The transferring, editing and playing back the recordings on all other devices on the network is perfect. You can even stream the recordings easily on an iPad or a laptop, or live and recorded images. TechniSat has obviously adapted the format of the recordings to the standards, so they can be played and edited easily on an iPad or laptop. The quality of the recordings is very good in HD as well as SD. The editing of recordings on the device is easy. The remote control has been redesigned many basic functions are now directly accessible by a button. In my view and for my purposes the Technisat ISIO DigitCorder C is perfect. The order, order processing and delivery by Amazon has been sound.
