I subscribed to SlingTV for a free 3 day trial to get NBCSN for the NHL Finals. I have some major issues with the service. I have a Roku TV, so some of it might be related to that.
1. Pause/rewind/recording/fast forward isn't available on all channels/programs/commercials. Yes, commercials. You can't just fast forward through them all, even on some previously recorded content.
2. Two times tonight, the stream jumped for no reason. During the hockey game tonight, it rewound by at least five minutes. I could not fast forward to get to back to where I was. On another show just now, I started watching the first few minutes then all of the sudden it jumped to minute 11. And its not easy to navigate back to where I was because of issue #1.
3. SlingTV with Roku interface is not channel surfer friendly. No easy way to search for a channel without continuous slow scrolling through 70ish channels. You can create a list of favorites, which helps, but I miss being able to type in channel numbers...
4. I pretty much only need a service like this for certain sports. Why am I paying $40-$70 per month to watch commercials? Plenty of content on Netflix and Amazon Prime, without commercials.
