Don't be shocked if there is a hiccup or two, especially early on. But those usually get worked out pretty quickly. I've watched Team State, the Semi-States (when I couldn't attend) and State for several years and overall have been very happy. For $25 you can watch all 4 SS and State next weekend and all matches are archived so you can watch them later as well. Definitely worth it!
Note: If you have an excellent internet connection and can cast a screen from your laptop, do so, it looks awesome. I watch one mat on my 65", a 2nd on my laptop and bounce between all 4 mats, using the TW Dashboard to keep me up on who's up on each mat.
