We cut-the-cord to cable several years ago..... and added Sling TV early this year. We're paying $20 for Orange (I think) package that includes things like ESPN, TNT, TBS, AMC, and many more. We also added the Lifestyle channels (eg. HallMark) for an additional $5. We prepaid for 3 months and received a free Roku device which we're using daily. We watch network channels with an antenna. We like the service, but it appears like they're still having some startup issues:
* Shows buffering, or hanging. We sometimes have to exit Sling app on Roku and re-initialize it. This is happening less and less, so I think they're getting a handle on their growth.
* The commercial breaks are 'interesting' . For example, the ESPN channel will often display a 'please standby' screen instead of commercials. Also, sometimes a commercial will play for a few seconds, be cut off for another commercial.
* One quirk of the Roku is that it doesn't have a power On/Off button. It's always there in standby mode. There were a few times where I wanted to power it off / on to reset a poor playback, so I had to pull the power cable for a few seconds. One thing I have done is plug it into a unique power strip which powers the Roku off whenever I turn the TV off. This is an easy way to reset the Roku several times a day, and keep SlingTV running smoother !
