I had one for a while since I am on the road half the time. Your success with it will depend on the two networks. If its just your parents home and yours and you both have solid, fast networks, then it will probably work great. If you are on a hotel network, it will just depend. Also, realize that if you are watching the slingbox and change the channel, it will change the channel on your parents TV too, because you are actually taking control of their cable box remotely. So I hope you and Dad like the same shows.
