My review on FB

The guide isn’t necessarily but it is if you want to “set it and forget it” for shows. If the network changes time or show changes channels, it will still record. Also needed if you want to use Tablo Connect, which let’s you watch on any device EXCEPT ROKU at any location. $5 permonth $50 per year, $150 per lifetime. Due to how it works,I recommend the 4 tuner. WARNING: IT DOES NOT SUPPORT DOLBY SOUND yet.
