Is there a charge for using Formular Z8?

Is there a charge for using formula Z8. I have viewed a couple of videos on formative Z8 and it says something about a premium charge. after looking at multiple videos I still don’t understand what they mean by a premium charge. Is there a charge for using that device

If you purchase it from an iptv co.they add there own program to it when you buy it.your actually buying the unit and they add the can buy the unit without the program on amazon.might be a couple dollars more but your not stuck with the program.hope this helps

Thank you, If I buy my own from Amazon, then I can put my SportzTV on it. Thank you
