Sling TV is the streaming service that also offers live TV over the internet. It’s essentially cable TV without the contract or the massive bill. Currently, if you sign up for Sling TV you get a Free Roku. They also offer a free 7-day trial membership to try out their service. The service works on every major OTT streaming device and recently began offering a cloud DVR. Sling TV also streams NBC live online along with Fox and ABC in select markets.
I like new Roku Streaming Stick+ quite a bit and have one set up on the TV in my bedroom. I spent several days testing it out with a couple of TVs around my house. The Streaming Stick+ is geared for 4K HDR, but can be used with TVs that only stream 1080p. I found it to be really solid with streaming Netflix and Amazon Video even when far away from my WiFi router. If you’re looking for lower priced streamer, then check out the new line of Roku media players. If any of them are out of stock at Amazon, you can buy them directly from Roku. Roku is currently offering a free trials of DirecTV Now and HBO Now with an activation of a new Roku device.
The question of "when does it make sense?" can easily be rephrased as "how much money can I save?" and one of the biggest factors will be the price difference between combined internet and TV service or just internet. These are also the options that vary the most widely based on where you live, and the availability of promotions or contracts that can keep prices down for a short time.
