I've had Netflix for years, got
Amazon Prime for the free shipping but also use the streaming as a bonus. Added Hulu several years back, I love all 3 of these services, especially after I upgraded to a Roku 3 from my previous Roku (I think the original version) as it didn't seem to stream Hulu very well, it would hick-up and glitch often.
Anyways I added Sling maybe 2-3 months ago and so far I'm not sold on it, it glitches more than any of my other streaming services, although admittedly I live out in the country with sub-par internet service (supposedly 10mbps) but it goes out often. Anyways this is to say Netflix, Hulu, and Amazon stream fine and work almost flawless now, but Sling glitches more often causing me to have to turn it off and restart it.
I'm not sure if I'll keep it yet, my wife would have already turned it off but I like the idea of the Disney channel for our kids.
