IKS only donation would be strictly good for FTA receivers, while IPTV + Free IKS will work on both FTA recover and IPTV boxes (MAG/AVOV) and emulators with the appropriate MAC address linked to the donation. IKS will be going out sooner then you know, and well IPTV is there to pick you up when IKS is gone. Choose the option for both as the pricing currently is only a 10$ difference for the time being.
