We have Spectrum TV here at home. To save money, I've gone without a cable box in my room since the beginning. After doing some research, I found out that Roku actually has a Spectrum app that works with a cable subscription, so I decided to order one. I figured it would be worth paying the $30 up-front cost of a Roku media player instead of paying a $10 per month rental fee for a cable box. So far, I think it's been well worth it.
The Roku Premiere hardware itself is pretty great. It's much smaller than I thought it would be yet is still able to play high quality 4k video. Included in the package is the Roku Premiere itself, a short HDMI cable, a power adapter and cable, the remote along with the necessary batteries, and some heavy duty double-sided tape to mount it to your TV. I originally planned on placing it behind my TV so that it could be hidden, but It does need line of sight if you want the remote to work, so that was a bit of a bummer. The device is so small that it really isn't that big of a deal however. I ended up mounting it to the bottom of my TV, and I barely notice it's even there.
The app selection is pretty great. The Roku channel is particularly nice because the video quality is superb, and it doesn't cost anything to watch. They just play a few ads every 15-20 minutes or so. Other apps are a bit hit and miss. The sole reason I bought the device (the Spectrum app) is a bit of a disappointment. It looks noticeably worse than the cable box version. The compression is pretty heavy, and I'm pretty sure they crop the channels as well. Still, it is nice finally being able to watch the Dodger games on a 55 inch TV from the comfort of my bed.
I still have a lot of other channels to search and test, but I'm already pretty satisfied with the few I've tried. For everything it provides, I think it's well worth the $30 price tag (I got it on sale), and the value can only go up as I find more useful channels to try out. I would definitely recommend it to anyone in a similar situation.
