From my experience as a hardware reseller and digital marketing for clients in the IPTV space, I can tell you that "lifetime IPTV" is never lifetime. Your device has a built in shelf life based on either the hardware (CPU/GPU/WiFi burning out) or the firmware and/or OS becoming outdated. Even IPTV services themselves go down, close, or are shut down all the time.

Your safest, cheapest, and least risky route is to get a solid Android device and IPTV subscription separately. Never add more than 3 months at a time to hedge your risk. And simply switch to a different provider if one goes down.
