I rarely watch TV, but when I do it's only for sports. My friend and I decided we would share the cost of a 1 month vader's subscription, and for the first 2 days it worked without issue for both of us. I live in the states and he lives in Canada. I knew a prime time football game would be the true test, as i'm sure the servers are loaded with concurrent connections. The first game I watched on ABC, and it was unstable until the game was clearly over. My buddy in Canada was experiencing the same issue, and IPVanish nor Nord VPNs made any difference. I was hoping things would improve tonight with the ESPN game, but it was even worse, and we both realized this service isn't for us.
I used Perfect Player, Kodi, the Vader's APK, and the website. None of these resolved the buffering and choppy playback, and the issue was clearly with the server being overloaded. I truly believe Vader's has been oversold, and it simply cannot handle the amount of concurrent connections one would expect for major events.
I have a fiber connection with 500mbps download and 200mbps upload. I'm not sure what my buddy in Canada has, but I know it should easily handle streaming based on the games we play together. The on demand content works great, and during normal viewing it also works great. If you are expecting to enjoy a prime time sporting event though, then get ready for constant annoyance.
I spent about 2 months exploring the world of IPTV. Even trying to watch HGTV on any of the providers was a constant annoyance.
